 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.
