This introduces a new configure option: --with-framework-name=NAME
(defaulting to 'Python'). This allows you to install several copies
of the Python framework with different names (such as a normal build
and a debug build).
way the resulting binaries have a better change of running on 10.3.
This patch also updates the search logic for sleepycat db3/4, without this
patch you cannot use a sleepycat build with a non-standard prefix; with this
you can (at least on OSX) if you add the prefix to CPPFLAGS/LDFLAGS at
configure-time. This change is needed to build the binary installer for OSX.
