Passing -undefined dynamic_lookup to the linker (instead of -lpython or -framework Python) permits undefined symbols in shared libraries on OS X. This allows a module to be linked against one Python framework and imported from another.

Tested by building ledger, which uses Boost.Python, against a version of Boost built with and without this patch. In the "before" gist, libboost_python-mt.dylib has a linkage to
/usr/local/Frameworks/Python.framework/Versions/2.7/Python; in the "after" gist, it does not, and the ledger python demo still runs correctly. https://gist.github.com/tdsmith/558243ad98ad288a16e0Closes #69.
