Slow Sfepy on Fedoracore 8

Hi,

I've compile sfepy un a fedoracore 8 64bit machine (8 cores) but some tests run very slow. The debug output show the test stopping a long time in lines like:

sfepy: nls: iter: 0, residual: 3.515775e-04 (rel: 1.000000e+00)

I've installed the latest numpy, scipy and umfpack scikits from source. I've installed (among others) the following devel packages:

atlas.x86_64 lapack-devel.x86_64 suitesparse-devel.x86_64

and inserted the section

[umfpack] library_dirs=/usr/lib64 include_dirs = /usr/include/suitesparse

both in numpy and in scipy site.cfg.

What may be the problem?

Thanks,

~ Antonio
