Compiz-0.9.8.0: string sub-command REPLACE requires at least

[yellowhat]

Hi all,
I am trying to update compiz from 0.9.7.8 to 0.9.8.0 using this ebuild https://github.com/shiznix/unity-gentoo/tree/master/unity-base/compiz.
But 0.9.8.0 gives me this error http://pastebin.com/raw.php?i=FnTbfsb2, seems to be releated to python but I don't know what to do.

Any ideas?[/code]

According to this bug https://bugs.launchpad.net/compiz/+bug/1004592, I should force the ebuild to use python 2. How can I do that?

If I "eselect python set python2.7" the problem is solved. But I want to set python3.2 for my system and python2.7 for compiz.

Solved adding on top of ebuild:
