Answer 1

which OS are you on?

first you need to install gsl and gsl-devel RPMs on your OS as root... e.g. on Fedora Linux:

sudo yum install -y gsl gsl-devel

then do the gem install gsl or bundle install

without the gsl-devel package, it will not find the correct C-header files.

You also need to make sure that those header files are installed in a location which is included in either the LD_LIBRARY_PATH, or listed in /etc/ld.so.conf
