Right, when the -lnpymath stuff got checked in. Looking at the build log you 
posted to numpy-discusson, it does appear that the $LDFLAGS is obliterating the 
intended flags. Please post a build log without setting those flags to 
numpy-discussion. A correct link line should look something like this:

gcc -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g -bundle 
-undefined dynamic_lookup 
build/temp.macosx-10.3-i386-2.5/numpy/core/src/umath/umathmodule_onefile.o 
-Lbuild/temp.macosx-10.3-i386-2.5 -lnpymath -o 
build/lib.macosx-10.3-i386-2.5/numpy/core/umath.so
