Yes, thanks, that works! Helmut

Is there a way to tell portage to use python3 by default then? I have it here so maybe it is already using python3? Anyway to know? I just tried eselect python set 2, the grepped ps when running an emerge --sync: # eselect python list Available Python interpreters: [1] python2.7 [2] python3.2 * # ps -ef | grep emerge root 6242 6127 2 22:29 pts/000:00:00 /usr/bin/python3.2 /usr/bin/emerge --sync So, just the usual.

I added that in package.use for future reference. That took out the python2 support. I also added this to make.conf: PYTHON_TARGETS=python3_2 I have it here so maybe it is already using python3?

It seems emerge is faster with python3. Now to sync and do some real testing. ;-) Thanks Neil and Adam. Dale :-) :-) -- I am only responsible for what I said ...
