[gentoo-user] All ~arch users: do not update python

[Nikos Chantziaras]

Updating python to 2.6.5_p20100801 will break portage.  emerge will stop 
working after that and there's no information on how to recover from 
that right now (because emerge won't work, you can't downgrade to the 
previous, working python version.)

Must not affect all users because it works for me:


[Orbitrap(84) ~]$ epm -q python
python-2.5.4-r4

/usr/bin/python3.1 emerge =lang-python/python-2.6.5-r3

Assuming of course you've got python3.1 installed in another slot.

Do you have the "python3" useflag set?  If so, emerge should be using
python3 not your eselected version.

Oh yeah, I'm using the python3 version of portage, that must be why.
