You should use nm to check for the symbol in your ATLAS libraries to
see if it's really missing or if numpy just can't find it.
nm -A /usr/local/atlas/lib/lib*.so | grep clapack_sgesv
nm liblapack.so | grep clapack_sgesv
On my machine, this produces
liblapack.so:000aff88 T clapack_sgesv
The "T" symbol means it's defined.
If the symbol is defined in your ATLAS libraries, then you should post
your site.cfg from numpy.
If it isn't defined, then you need to rebuild the ATLAS libraries.
Enjoy global warming while it lasts.
