Comment(by blb@…):

 What's interesting is that the section of distutils/sysconfig.py where
 this is occurring, is code that is processing MACOSX_DEPLOYMENT_TARGET.
 It's splitting MACOSX_DEPLOYMENT_TARGET on '.' so should be comparing, eg.
 10 to 10 and 5 to 5.  Instead it is failing to convert what it gets from
 the split to an integer, so it must not be seeing 10.5 in that.

 cfg_target should be coming from ${prefix}/lib/python2.5/config/Makefile
 and cur_target from the environment (which is set by port).  For anyone
 who is experiencing this issue, can you attach that Makefile to this
 ticket for review?
