For the past several weeks, I have been unable to build numpy from
source, at least nothing that works. The issue is that symbols appear
to be missing from umath. When numpy is imported, I get the following:

I think my build script is good, but here it is just incase:
#!/bin/sh
export MACOSX_DEPLOYMENT_TARGET=10.6
export CFLAGS="-arch x86_64"
#export FFLAGS="-arch i386 -arch x86_64"
export FFLAGS="-arch x86_64"
export LDFLAGS="-Wall -lgfortran -undefined dynamic_lookup -bundle -
arch x86_64"
rm -rf build
python setup.py config -L/Users/fonnesbeck/Code/freetype -L/Users/
fonnesbeck/Code/libpng build
python setupegg.py egg_info --tag-date bdist_egg
I'm at my wits end with this one, so any help at all is most
appreciated.
Don't specify LDFLAGS if you don't have to. It is obliterating the -l flag for
the npy_math library that numpy builds internally and tries to link with.
