If you have a new Lion (OS X 10.7) installation without gcc-4.2, your numpy
distutils will probably try to link with clang, which ignores the LIBRARY_PATH.
If you link with gcc, it may get confused by the i386 and x86_64 bundle.
You can fix both of these problems by first typing the line::

$ export LDSHARED='gcc -bundle -undefined dynamic_lookup -arch x86_64'
