Okay - the website seemed to indicate dependence on various things that have fortran, but it did say "weak" dependence so maybe the core functionality doesn't need that? "GSL requires a BLAS library for vector and matrix operations" but maybe that doesn't have to be fortran, or maybe that's irrelevant to the main numerical stuff one would care about.
