That's strange. I doubt that any software available on 64 bits are not
available on 32 bits.

Again, without the full build log, we can't really help you. I would
guess that your blas/lapack is not built correctly. Are you using
blas/lapack from netlib ?
You should really use packages first, and only if it does not work, try
to build from sources.
