I had a look at the package and checked with opensuse 11.3 and octave 3.3.52 
with gsl-1.0.8 that the make file in the src folder of the gsl-1.0.8 package 
defines

#LIBGSL=$(shell gsl-config --libs-without-cblas)
LIBGSL=-lgsl

which leads to that problem since the resulting oct file is not linked against 
libgslcblas as it should in that case (the unresolved symobol is in gslcblas). 
I checked simply with ldd.

changing that manually to 

LIBGSL=$(shell gsl-config --libs)

results in a successfull compilation and in a psi function which does not show 
the runtime error and gives correct results.

Since I do not understand enough about packages, makefiles and so on, I do not 
know if that is a bug in the gsl package or in gsl or in opensuse.
