Well, I'm still reading this forum.

Unfortunately I'm not on a 64 bit architecture, and this problem may be
peculiar to it. I guess to be of more help I'd have to see some outputs
from your compilation of both lapack and atlas. Are you using g77?
After hassles with Absoft, and finding that g77 was actually better in
most instances as measured by the LAPACK timing tests, I used g77
throughout for my LAPACK and ATLAS compiles. For LAPACK, I used the
supplied make.inc.LINUX file as make.inc, with the exception that I
removed the '-fno-f2c' switch. A simple 'make config' then worked fine
for me with ATLAS. The LAPACK compile doesn't seem to use -fPIC, which
shouldn't be needed anyway; neither LAPACK nor ATLAS can easily be
installed as shared libraries anyway, which is why Fernando Perez has
his scripts to build separate versions of Numeric/numarray/scipy/etc.
statically linked against various hardware-specific versions of ATLAS.
This is a bit of a ramble; hope some of it helps.
