scipy 0.3.2 does not have fftw3 support, it's only available in CVS/SVN
version of scipy. You can either ignore it (since scipy uses fortran 
fftpack instead fftw), or install fftw2, or get scipy/scipy_core from SVN 
repository.

This looks like a numarray/Numeric issue. For some reasons Numeric imports 
dotblas from numarray package.
