3930	More flexible dynamic linking for python module on OS X	Cyrus Omar	Dave Abrahams	"See http://trac.mapnik.org/ticket/453/.

Without these patches to python.jam and darwin.jam, boost.python refused to build with the following error for me on OS X 10.6 (Snow Leopard), even when I set my path to use a version of Python (from Sage) which was compiled with UCS4. With these changes, you can build against both system Python (UCS2) and Sage Python (UCS4). This should probably be incorporated directly into boost, it took me several hours of headaches to figure this out.
