thanks Martin,
with your changes it works finally !
however, entering

pkg install gsl-1.0.8.tar.gz

octave spits out a lot of warnings like
/usr/lib64/gcc/x86_64-suse-linux/4.4/../../../../x86_64-suse-linux/bin/ld: 
skipping incompatible /usr/lib/libm.so when searching for -lm
but it does not seem to hurt, because psi(1.) returns the correct answer;
