ok. I'll forget about the other errors I have and will focus on
libsunperf for now. It makes sense to me to use vendor provided
optimized BLAS/LAPACK libraries.
I compiled with these options :
python setup.py config_fc --f77flags='-xlic_lib=sunperf -xarch=v9b' install
and now, I've got this error when importing numpy :
ImportError: ld.so.1: python: fatal: relocation error: file
symbol dgeev_: referenced symbol not found
