from a 'Forge package'

I first sent an email to the gsl package maintener, Teemu Ikonen,
but he can no longer be reached under address@hidden;

I found a post of someone, Bob Odom,  who experienced something quite similar, 
using also SuSE:

http://www.mail-archive.com/address@hidden/msg03577.html

however, they used RPMs, and, for Martin Helm, it worked using gsl 1.12,
for Bob Odom, mysteriously, it failed, he had to install instead the gsl 1.11;
I for myself tried it using gsl 1.10, 1.12 and 1.14 (the latest stable); it 
always failed;
notice: I compiled and installed the gsl libs instead of relying on the RPMs.

since I do only need the psi (=digamma) function, I decided to code it using a 
brute-force approach,
i.e. simple finite difference;
in fact, it would be nice if this function were part of octave,
since it is also part of Matlab, but I refrain from opening a request since 
one could argue that there is an octave package for that;
