I run 32-bit Debian on my Core 2 Duo box. ATLAS detects the Core 2 Duo and attempts to do a 64-bit build, which fails with errors like this:

(Note the "-b 64" at the beginning of the above, which means to do a 64-bit build.)
Adding "-b 32" to the configure line in spkg-install allows the build to proceed.
