Attention it seems not working with Ruby 2.1.0.

For Ubuntu 12.04 LTS and Ruby 2.0.0:

cd ~
wget ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz
tar xvzf gsl-1.15.tar.gz
cd gsl-1.15
./configure
make
sudo make install

Check if GSL 1.15 is correctly installed

gsl-config --version

Then install gem (gsl 1.15.3)

gem install gsl
