Gentoo Portage Python Update issues

I have been having some gentoo portage problems due to my system being out of sync. When I finally updated a month or two later, it simply wasn’t working. I was getting an error like the following…

The solution is simple, but not necessarily easy to think of.  All that needs to be done is to move the 4Q-2009 and 3Q-2009 files somehwere else, and then update python/portage.

[19:31 root@joseph updates] # eselect python list                    
Available python interpreters:                                       
 [1]   python2.4                                                    
 [2]   python2.5 *                                                  
 [3]   python2.6                                                    
[19:31 root@joseph updates] # eselect python set 3
[19:35 root@joseph updates] # emerge -1 portage

Then, move the 4Q-2009 and 3Q-2009 back to the proper locations, and everything should be working.  Next, it’s probably good to do a “python-updater -p”, followed by your world update.
