Already tryed to solve using
$ sudo apt-get install postgresql-client libpq5 libpq-dev
then:
$ sudo gem install pg
That is because you have not set the write permission to the directory,try:
chmod +777 /var/lib/gems/1.9.1
You need to install the -dev part of the Ruby package. Something like:
sudo apt-get install ruby1.9-dev
should give you the parts of Ruby necessary to compile binary extensions.
Good luck!
This help me:
sudo apt-get install rails
I got almost the same problem.
I use this to solve it.
$rvmsudo gem install pg

stuff that may help?

Based on your locate command, you have mkmf in rvm and in ubuntu's home diretory, but not on the system, and you're explicitly using the system's ruby (and not rbenv or rvm) to run the extconf.rb. Either run a ruby from one of the environments you have mkmf in, or install the ruby-dev package on the system.
I am installing riemann monitoring tool on my PC. I run the following command from terminal:
Command:
sudo gem install riemann-tools
I get the following error:
ERROR: Error installing riemann-tools:
ERROR: Failed to build gem native extension.

A similar error comes when installing riemann-dash but riemann-client get installed successfully.
I am using Ububtu 12.10.
I read online about such errors and it had something with ruby version, but I am not able to figure out the reason for this.
Any help is appreciated.
this solved it for me:
For Debian/Ubuntu
apt-get install ruby-dev zlib1g-dev
For RedHat/CentOS/Fedora:
yum install ruby-devel zlib-devel

you need ruby-dev
sudo aptitude install ruby1.9.1-dev
should fix it.
When I run sudo gem install nokogiri on Ubuntu 12.1, I'm returned with this. What's wrong and how do I fix it?

mkmf is part of the ruby-dev package if I'm not mistaken. Try:
sudo aptitude install ruby1.9.1-dev
Of course you may be better off installing ruby through RVM :)
For ubuntu 13.04, this is what worked for me:
sudo apt-get install ruby-dev
try
rvm all do gem install nokogiri
