gsl package: undefined symbol: cblas_ctrmv

[lo]

hello,

under octave 3.3.51 on SuSe 11.2 I installed the gsl package 1.0.8;
I want to use the psi (=digamma) function;
so, after the installation at the octave prompt:
psi(1.)
but it fails and I got:

error: 
/usr/libexec/octave/packages/gsl-1.0.8/x86_64-unknown-linux-gnu-api-v39+/gsl_sf.oct:
 failed to load: /usr/lib/libgsl.so.0: undefined 
symbol: cblas_ctrmv

I read in a post that it could be possible to preload a shared library;
so I tried:

LD_AOUT_PRELOAD=/usr/lib/libgslcblas.so.0 octave

but psi(1.) returned the same error message;

thank for any help,

regards,
Laurent
