Well I've never used mkoctfile but I've built lots of things that need
to be linked to things, so I'll just pretend it's gcc.

Try, just -lgsl -lgslcblas. The linker knows to look in 'standard'
places like /usr/lib, and it knows that libs have standard names like
libBLAH.so. I just installed the devel package just to check and it
looks like you are on the right track.

One thing that you might have to worry about though is a conflict
between blas libraries. I don't know if this is actually a problem but
you could easily get atlas, gslcblas, and regular Fortran blas all mixed
up. GSL can use a different cblas than the minimal one that it comes
with.
