Fransesc,
I don't think that's the problem-I'm working with a version of numpy I had
downloaded back in Dec/Jan and have not updated it since.

However, doing a "LD_PRELOAD" seems to have fixed the problem, but now
whenever I'm running a script I get:

 python 2.4.3 GCC 4.1.2 20070626 (Red Hat 4.1.2-14) 64bit ELF on Linux
x86_64 redhat 5.2 Final
python: symbol lookup error: /opt/intel/mkl/
10.0.3.020/lib/em64t/libmkl_lapack.so: undefined symbol: mkl_lapack_dgetrf
