bug: python3 becoming system default

Recently there was a bug in stage3 tarballs resulting in python3 being the default system python (such configuration is not supported yet and may result in various breakages).

If you installed recently, I'd recommend checking the system python version. The correct result should look like this:


# eselect python show
python2.6

For more information see bug #330655. The problem is now fixed, new stages are correct. To fix an existing installation, use "eselect python list" and "eselect python set" to switch to a python2 version.
