I can succesfully install the gsl library in my home directory, but when I try to install the gsl gem I get a big list of errors that I do not understand. I am wondering if someone could give me some idea why I could be getting those errors. I can say I have:
Installed gsl succesfully; at least that is what it looked like. I pointed the path to gsl-config
This is what the error log looks like:

Answer
Install ruby GSL:
Ubuntu 11.10 includes a newer version (1.15) of libgsl0 that is not compatible with ruby/gsl :
Must install older version 1.14 for ruby/gsl to work:
curl -O http://mirror.veriportal.com/gnu/gsl/gsl-1.14.tar.gz
tar xvzf gsl-1.14.tar.gz
cd gsl-1.14
./configure
make
sudo make install
sudo gem install --conservative --no-ri --no-rdoc gsl
Installation works OK and test on Ubuntu and Debian Squeeze:

Fetching: gsl-1.14.7.gem (100%)
