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.
