is too old and today there are other ways to build wrappers . I can suggest
to see SWIG (http://www.swig.org),  there is a very good section on  Lua.
In any case the filter module that you use is often  a reliable
alternative to connect to external programs, so the problem
is often to be sure to have a good program. In your case you can also write
a python script that uses that gsl module (if there is such module, I
don't  know exactly) and then call python by mean of the filter module.
