Tim D. Smith d057828ee3 Don't explicitly link Python on OS X
Explicitly linking to a Python framework on OS X prevents modules from
being built against one python (i.e. system python) and imported from
another (i.e. Homebrew python); the interpreter segfaults if there's a
linkage to a foreign python. Building the module with `-undefined
dynamic_lookup` instead of an explicit link allows the symbols to be
resolved at load time from a compatible python.
