>Severity:	serious
>Priority:	high
>Category:	ports
>Class:		sw-bug
>Release:	FreeBSD 8.2-STABLE amd64
>Environment:
System: FreeBSD datakitty.lan.rachie.is-a-geek.net 8.2-STABLE FreeBSD 8.2-STABLE #6 r230977: Sun Feb 5 06:20:11 AKST 2012 mel at datakitty.lan.rachie.is-a-geek.net:/data/obj/data/RELENG_8/src/sys/GENERIC amd64


>Description:
Incompatibilities with python 3.x cause several commands in bsd.python.mk
to fail.
The net result is that when python 3.1+ is installed, any port setting
USE_PYTHON will pull in the default python version and several variables
that should be available to dependent ports are not.

>How-To-Repeat:
Install lang/python31 (uninstall lang/python27 if installed).
make -C /usr/ports/devel/talloc -V BUILD_DEPENDS

>Fix:
