If you're running a stable system then you should not *need* to define a 
particular python version or python target manually in your USE preferences 
configuration and you should not need to add python or any lib packages in 
general, in your '/var/lib/portage/world' file.

Portage will take care of python for itself and for any packages which have 
python as a dependency.

eselect python list
eselect python update
eselect python cleanup

and running emerge --depclean -v -a

after a new python version arrives should keep your system stable without any 
more clashes, in most cases.  The devs usually do a very good job in leaving 
the stable tree in a ... stable condition.  :-)
