Hi Christopher and all others! A few months ago I did the same and published it under: http://www.zpr.uni-koeln.de/~achim/gsl/ I use the setup tool that comes with python and have excellent results on sun and linux (suse, redhat 7.*) with python 2.* . It is better to sum up our results I think. If you (or anyone else) likes to add some stuff, download my module and modify it! Yours Achim PS: - The version number is very low, just because I had no time to improve it. - I was confused by some odd behaviours of the gsl.m4 macro, maybe it is better to fix them (I one week I'll have to work with gsl and c++ too).
