Need help configuring ImageMagick - ruby-on-rails

I've directly downloaded the tar file from here onto my desktop for Mac OSX (which is what I'm using) and extracted its contents. Now I've read the following instructions on how to set it up, but honestly they're a bit too cryptic for me. I was wondering if anyone could please break down these instructions into simpler, bite size pieces for someone who typically has trouble configuring new things...
I'd truly appreciate any help! Thanks!
Btw, my end goal is to set this up for the Paperclip plugin.

The first step would be to install MacPorts if you don't have it already. Once MacPorts is installed it should be fairly straightforward based on the instructions listed at the link you provided.
sudo port install ImageMagick
For others interested in this topic, I might look into installing homebrew instead of MacPorts.

Installing VIM in Minix 3.1.8

I've Googled this a thousand times and I cannot, for the life of me, get VIM to work on my Minix 3. For the record, I am running on a Windows machine with Minix 3 working on Oracle's VM VirtualBox.
I've tried typing,
# pkgin up && pkgin in vim
but I get the error:
pkgin: Can't open database /usr/var/db/pkgin/pkgin.db: unable to open database file: No such file or directory
I then try to do pkgin search git to search for a package, but I get the same error. Could this be some kind of Internet connection issue? I'm incredibly confused.
If you haven't already, download the binary package from here:
ftp://ftp.minix3.org/pub/minix/packages/3.3.0/i386/editors/
Change "i386" to your correct architecture, if different.
As you're probably already familiar, this page tells you how to install binary packages for Minix:

As far as your "pkgin" errors, here are two possible solutions:

How to install vim into Minix3?
I asked on the Minix 3 Google Groups Forums and they solved my problem. If anyone else has trouble, I'm pasting a response by Lionel:
Switch to http downloads by editing "/usr/pkg/etc/pkgin/repositories.conf" and comment out the line:
ftp://ftp.minix3.org/pub/minix/packages/$osrelease/$arch/All
and add the following:
http://www.minix3.org/pkgsrc/packages/$osrelease/$arch/All
Then do shutdown, boot, pkgin update and then install your desired packages.

Do I Really need to install homebrew to install rails and why?

I hope this question is suitable for this forum, I'm still learning what's deemed fit and what isn't. Anyway here is my question, a lot of places seem to state I need to install homebrew on my mac to install rails, do I really need to and what benefits does it offer to do so and for the development environment?
This question is pretty bad but I remember when I started programming that I had a similar question, so here we go:
How do you install stuff on your computer? Obviously you use the Mac App Store if you want something from Apple, and if you want to install Chrome just go the Google Chrome website etc.
But when you want some kind of programmer tool, let's say a compiler. How do you install this? Either you go to their website, download a tarball with the source code, compile it from scratch and bind the necessary environment variables. Or you are unlucky and the compiler has a bunch of dependencies so you have to download them first.
Then some geniuses thought that "Oh damn, that's a pain", so instead they created so called package managers, so now when I want Rails on my computer, I just installed it through the "gem" ruby package/dependency manager.
So you can install rails through the command "gem" (just google "ruby gem") and you'll see what it is, but I advise you to if you want to have a nice development environment where it's easy to install and uninstall stuff, use brew or macports.

Dealing with a large c++ library in a Rails deployment

I have a Rails project that is going to be using OpenCV, and it depends on a certain version of it (2.4.6.1).
I'm looking for deployment advice. The Ubuntu opencv package is an earlier version and therefore not suitable.
I can see a number of possibilities, but I'm trying to think of what will work best.
Just write it up in a README and expect people to follow it: download this, apt-get that, etc...
Add opencv, tagged at the version we need, as a git subtree, and include a Rake task to build it.
Write a script to download and compile the needed code.
Something else ?
None of them seem all that great, to tell the truth.
Can your application be made to work with OpenCV 2.4.2? That is available in Ubuntu 13.04, and you could request it be backported to 12.04. If not, you could update the source package to 2.4.6.1 (which would require learning about debian packaging but might not be too difficult since you would be modifying an existing package instead of starting from scratch), upload it to a PPA, and instruct your users on Ubuntu to install OpenCV from there. You could also package your rails application and put it in the PPA, which would make overall installation even easier.

New to vim - MAC OSX Mountain Lion

I am new to vim, and I just followed this setup tutorial, but something went wrong. I am a ruby developer and I am not getting a a ruby highlighting syntax. I have installed janus, before with pathogen I had syntax highlighting but not know.
Also I am using the solarized theme the guy suggested but there is no difference now (in color) between folders and files in my terminal when listing a directory.
Could somebody tell me if I can install pathogen with janus? WIll this break my vim?
Thanks!
Don't install anything (and don't install Janus).
Run $ vimtutor in your terminal. As many times as needed (and don't install Janus).
Once you feel ready to use Vim for day-to-day coding, install MacVim which is built with a better feature set than the default Vim. It comes with a CLI executable so you can use it in your terminal and in tmux (and don't install Janus).
Install the vim-ruby package for better, more up-to-date Ruby support (and don't install Janus).
Don't install Janus. This thing is a pile of crap that will make your life overly complicated, hook you on plugins that may or may not be the best for you needs and prevent you from actually learning Vim properly in exchange of an artificially flattened learning curve.
Decide for a plugin/runtimepath management solution (VAM, vundle or plain Pathogen) and choose your plugins yourself according to your needs (and don't install Janus).
If you have problems with Solarized, take a look at their issue tracker and their wiki. It is fragile and you need some work to set it up correctly (and… you know the rest).

From the website for rails.vim.
