Sourceforge have a couple of OS X boxes, so I've just tried building the
Python bindings on OS X 10.1.4.  I can't get it to link with or without
MACOSX_DEPLOYMENT_TARGET set (or whatever I set it to).  The other box
was 10.2.8 last time I checked but it's currently down.  When it comes
back I'll check there too.  If that fails to link whatever
MACOSX_DEPLOYMENT_TARGET is set to, there's really no argument for not
setting MACOSX_DEPLOYMENT_TARGET.
