It appears my USE flag combination requires Python 3 but the ebuild doesn't check for that. I'm using Python 2 because some of my scripts/plugins still require it.

Reproducible: Always Steps to Reproduce: 1. emerge weechat 2.7 with the abovementioned USE flags Actual Results: Configure fails. Expected Results: Build against Python 2 or fail early with a USE flag conflict message. If 2.7 can't work with Python 2 at all, drop the target USE flag.
