I did not see this with scipy0.9rc3 using any of the various Python 
versions (still need to get Python 3.2) on my 64bit Fedora 14 system 
which does not have any Intel compilers or libraries.

Do you get this error with Python 3.1?

Also, with regards to Pauli's last comment on ticket 1233, it would be 
interesting if using fwrap instead of f2py helps.
