Error trying to install rinku gem on mac - ruby-on-rails

I'm having trouble installing the rinku gem version '1.7.3' on Mavericks. I followed the advice of another post that suggested to install apple-gcc42 but that didn't help. I've also tried searching google and stack overflow but couldn't find this exact issue. Here is the error:
Building native extensions. This could take a while...

Error installing kdtree

When I tried running my Ruby code with bundle install, I encountered this error: Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
I tried running gem install kdtree and gem install kdtree -v '0.3' but it throws me the same error as well. Now I am unable to run my Ruby code. Any ideas on how to resolve this. I am running on Windows machine btw. Here's the full error log:

Make sure that `gem install binding_of_caller -v '0.7.2'` succeeds before bundling.
i cannot understand whether this error related to any dependency problem or am i checked out an wrong version.
Please help me out.

You are using a ruby version (1.8) not supported by binding_of_caller and also not supported by OpenProject . You will need to install ruby 2.1.
If possible on Oracle Linux, I would recommend doing this via RVM or rbenv.

I don't see this in the installation guide on Ubuntu, but this answer recommends:
You need to install ruby-debug first passing the include directory.
gem install ruby-debug -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p362
(adapt it to your ruby version)

make: *** [WelcomeWagon.all.tweak.variables] Error 2
Could anyone tell me what I'm doing wrong? Thanks in advance.

I found the same problem with current version of Ryan Petrich's dumped headers today.
Finally I find out that the solution is,
Import the dumped Springboard headers
Copy /System/Library/Frameworks/IOSurface.framework/Headers/IOSurfaceAPI.h to /opt/theos/include/IOSurface. The reason is in IOSurface/IOSurface.h!
If you are running OS X Lion or later, you may need to comment out the following lines in /opt/theos/include/IOSurface/IOSurfaceAPI.h:
/* This call lets you get an xpcobject_t that holds a reference to the IOSurface.
Note: Any live XPC objects created from an IOSurfaceRef implicity increase the IOSurface's global use
count by one until the object is destroyed. */
// xpc_object_t IOSurfaceCreateXPCObject(IOSurfaceRef aSurface)
// IOSFC_AVAILABLE_STARTING(_MAC_10_7, __IPHONE_NA);
/* This call lets you take an xpcobject_t created via IOSurfaceCreatePort() and recreate an IOSurfaceRef from it. */
// IOSurfaceRef IOSurfaceLookupFromXPCObject(xpc_object_t xobj)
// IOSFC_AVAILABLE_STARTING(_MAC_10_7, __IPHONE_NA);
Give it a try!

I just did this today 02/13/2013 and found the above to be somewhat helpful. With a little brains and the help of Google I found that what you need to do is :
1.) Get the headers - use a Google search for "Ryan Petrich's dumped headers" which will lead you to :https://github.com/rpetrich/iphoneheaders
2.) Use git to clone the repo : git clone https://github.com/rpetrich/iphoneheaders
3.) run make ( I found that I needed to run make as sudo make due to the location of theos being installed under /opt. )
4.) For each "error file not found" I copied the include files into my project.
5.) I believe you should end up with the following folders in your project folder :
AccountSettings IOKit SpringBoard
ActorKit IOSurface TelephonyUI
AppSupport JavaScriptCore Tutorial.plist
Availability2.h MIME Tweak.xm
ChatKit Makefile Tweak.xm.original
CoreFoundation MediaPlayer UIKit
CoreGraphics Message WebCore
DAVKit MessageUI WebKit
DataAccess MusicLibrary control
Foundation PhotoLibrary obj
GraphicsServices QuartzCore theos
6.) You need to do #2 from the answer above "Copy /System/Library/Frameworks/IOSurface.framework/Headers/IOSurfaceAPI.h to /opt/theos/include/IOSurface. The reason is in IOSurface/IOSurface.h!"
7.) You also need to make the edit from the answer above "If you are running OS X Lion, you may need to comment out the following lines in /opt/theos/include/IOSurface/IOSurfaceAPI.h:"
/* This call lets you get an xpcobject_t that holds a reference to the IOSurface.
Note: Any live XPC objects created from an IOSurfaceRef implicity increase the IOSurface's global use
count by one until the object is destroyed. */
// xpc_object_t IOSurfaceCreateXPCObject(IOSurfaceRef aSurface)
// IOSFC_AVAILABLE_STARTING(_MAC_10_7, __IPHONE_NA);
/* This call lets you take an xpcobject_t created via IOSurfaceCreatePort() and recreate an IOSurfaceRef from it. */
// IOSurfaceRef IOSurfaceLookupFromXPCObject(xpc_object_t xobj)
// IOSFC_AVAILABLE_STARTING(_MAC_10_7, __IPHONE_NA);
FYI in my IOSurfaceAPI.h these were lines around line number 252/253

You don't need to import the dumped Springboard headers.

OpenKinect: Cannot build RGBDemo

I am following the instructions given in the book "Hacking the Kinect" pages 15-16 (Apress 2011) to install the RGB Demo (version 0.5.0) on my system (32bit x86 machine running Xubuntu 12.04).
I downloaded and extracted the demo's source and installed the needed packages as described within the book:
libboost-all-dev, libusb-1.0-0-dev, libqt4-dev, libgtk2.0-dev, cmake, ccmake (from cmake-curses-gui), libglew1.5-dev, libgsl0-dev, freeglut3-dev (not libglut3-dev as stated in the book), and libxmu-dev.
Note book typo: libgs10-dev should actually read libgsl0-dev.
When running ccmake on the source's root directory, I set the flags as given by the book:
BUILD_EXAMPLES ON
BUILD_FAKENECT ON
BUILD_SHARED_LIBS ON
NESTK_USE_FREENECT ON
NESTK_USE_OPENNI OFF
NESTK_USE_PCL OFF
and leave all other flags as their defaults.
I then proceed to configure and generate without issue, but when subsequently running make, I run into the following error:

What is causing these errors and how do I resolve them?

Could it be as simple as opencv/modules/core/include/opencv2/core/core.hpp missing #include <stddef.h>?

Yeah just edit the core.hpp /home/linaro/Downloads/RGBDemo-0.4.0-Source/nestk/deps/opencv/modules/core/include/opencv2/core and add the line
#include <stddef.h

Did you see the instructions on the bdb page?
As a Gem
At the moment this library is not available on RubyForge. To install
it as a gem, do the following:
[sudo] gem install bdb
For Berkeley DB v4.7 installed from MacPorts do
the following:
[sudo] env ARCHFLAGS="-arch i386" gem install bdb This assumes you're
on OS X and BerkeleyDB wasn't compiled as a universal binary.
So it looks like you need to install berkeley db via macports/brew to get the Gem to install.
