The problem goes away when /usr/local/lib/libfftw3.a is moved.

Comment (by mabshoff):
This problem can be fixed by patching the default locations the build
system looks for libraries. We should disallow /usr and /usr/local and on
OSX the various places for Fink and MacPorts since more than likely some
random crap will be pulled in that way.
Cheers,
Michael
