Ok, now I see where is the problem, I think. Try
ls -l /usr/local/lib/liblapack.a
The size of this file should be aroung 6MB. If it is much less than that
then you have incomplete lapack. To get a complete one, follow these
Fernando, can you add the remark above also to
? Also, the manual linking part in the fftw section is
unneccasary: system_info.py should be able to handle it now.
Finally, can you make also a link to INSTALL.txt file? This file should be
the most up-to-date document about building SciPy.

Let's first try to get scipy working without too much changing the system.
According to the system_info.py output, nothing needs to be removed from
your RedHat installation, I think.
