unable to install Gosu library in Ruby in Linux

I am getting this error when I am trying to install gosu on Ubuntu 13.10

Fetching gem metadata from https://rubygems.org/.........
Fetching version metadata from https://rubygems.org/..
Resolving dependencies...
Using diff-lcs 1.2.5

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

The Gosu gem requires some libraries to be installed system-wide.

                               ^

I tried adding every library from https://github.com/jlnr/gosu/wiki/Getting-Started-on-Linux, but I am still getting the above error. Can anyone please help me with this?

Edited: When I check for status of installed packages as

 dpkg -s gcc libsdl2-dev libsdl2-ttf-dev libpango1.0-dev libgl1-mesa-dev libfreeimage-dev libopenal-dev libsndfile-dev | grep Status

I get the following status:

Status: install ok installed
dpkg-query: package 'libsdl2-ttf-dev' is not installed and no information is available
Status: install ok installed
Status: install ok installed
Status: install ok installed
dpkg-query: package 'libopenal-dev' is not installed and no information is available
Status: install ok installed
dpkg-query: package 'libsndfile-dev' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

So, libsdl2-ttf-dev and libsndfile-dev are not installed. I tried installing these packages with apt-get install, but was unable to install them as it says the packages could not be found in any sources.

are you sure all of dependencies are installed correctly ?

first please check them :

dpkg -s gcc libsdl2-dev libsdl2-ttf-dev libpango1.0-dev libgl1-mesa-dev libfreeimage-dev libopenal-dev libsndfile-dev | grep Status

then , you can check the problem easily ! you have to check the install log file :

you can open the file with editor like vi , nano , or cat , tail ... , I've used nano 

nano /var/lib/gems/*/gems/*/ext/gosu/gem_make.out

move to end of the file and check why make the script stopped ! post the Error Here , then i can help you for resolve the issue !
