>Description:
The default python version list defined in Mk/bsd.python.mk @205 lists version 3.1 higher then 3.2:

_PYTHON_PORTBRANCH=     2.7
_PYTHON_ALLBRANCHES=        2.7 2.6 2.5 2.4 3.1 3.2# preferred first
_ZOPE_PORTBRANCH=       2.7
_ZOPE_ALLBRANCHES=      2.7 2.8 2.9 2.10 3.2

This means for any package marked as 3.1+ 3.1 would be preferred version and 3.2 would be ignored.
>How-To-Repeat:
For example try compiling databases/py-postgresql having lang/python32 installed - it will default to building lang/python31.
>Fix:
Why not order list by version?

_PYTHON_ALLBRANCHES=        2.7 2.6 2.5 2.4 3.2 3.1# preferred first

This will revert to old behavior when higher version would be accepted if lesser version is required.
