Hm, did you read the link I cited? It's not so surprising that 3.0
should have broken distutils, but what I found distressing is that they
fixed distutils and then 3.0.1 broke it *again*. I stand by my opinion
that Python 3 isn't stable yet.

One other thing that we'll have to seriously consider is whether we
should package python3 as a separate PL, so that people can keep using
their 2.x plpython functions without fear of breakage. I know that the
Fedora guys are currently debating whether to treat it that way, and
I suppose other distros are having or will soon have the same
conversation. Six months from now, there will be some precedents and
some track record for us to look at in making that choice.
