Hello, Since some ebuilds are using that variable already and we still didn't inform most of our users if and how they should set it, I'd like to commit the following news item:
Title: PYTHON_TARGETS deployment

Lately, a new Python eclasses were deployed and the way of supporting
multiple Python implementations changes with ebuilds being migrated
to them. While before the implementations being installed were used
by default, the migrated packages will instead use explicit choice based
on PYTHON_TARGETS USE flags. This may require action from some of our
users.
If you are running a modern system with Python 2.7 & 3.2, and you didn't
set USE_PYTHON, then you don't have to do anything. The defaults
will fit you.
Otherwise, you will want to set PYTHON_TARGETS in your make.conf file.
This is a regular USE_EXPAND variable listing requested Python
implementations like:
PYTHON_TARGETS="python2_7 python3_2 pypy1_9 jython2_5"
The variable should list all requested Python implementations.
A complete list of possible values can be obtained using a command like:
emerge -1pv dev-python/python-exec
