py-gnome2-desktop and python 33

[Richard PALO <richard.palo%free.fr@localhost>]

Guess I'm a glutton for punishment having rebootstrapped and runnig with 
gcc48 and PYTHON_VERSION_DEFAULT=33 in options.mk...
decided to build meta-packages/gnome and it choked on 
x11/py-gnome2-desktop because above is not 27 or 26.

Up to that point everything gnome built was quite happily '27'.

This following patch seems to get over the "issue" but before 
committing, any objections?  (Can't find any doc/use of the 
'PYTHON_VERSIONS_REALLY_ACCEPTED' variable in the Makefile...)
