python3: xorg-libxcb @1.7_0 fails to build

Description
I actually found a fix in between opening this page and posting this.
Basically, I was upgrading xorg-libX11, which depended on xorg-libxcb. When Macports tried to upgrade that, it hit a build error and exited. looking into the log, I noticed that it was trying to build a python file by calling /opt/local/bin/python and running into a syntax error. I have python_select installed, and at the time it was currently set to python31. Noticing that one of the arguments was a python26 framework, I switched python_select over to python26. Worked like a charm.
So the port is calling something that if you have python_select installed, is in fact a symlink.

gotyai: Solid tip. I did the following to get python_select all set up:
sudo port install python_select sudo python_select python26
and that worked for me as a workaround too. I'm attaching a debug.log file showing how xorg-libxcb is failing to build.

hmm, it appears our debug logs differ. I recreated the problem, so I could post mine.

Thanks for the tip!
Didn't have python_select installed, and once it was installed all "python_select -l" would show was current, none, python26 and python26-apple. Don't know which was set from the get-go, if any (perhaps python26-apple?), but setting it to python26 as proposed here worked like a charm!

Do you have a patch to make it work with python 3?

Attached patches fix syntax for python3 by running 2to3. A couple of other fixes are also needed as referenced from https://bugs.freedesktop.org/show_bug.cgi?id=36188 -- a circular import in xcbproto and an attempt to compare None with a number in libxcb. These are taken care of by the patchfiles.

Please send these patches upstream (attachint them to the bug report referenced will help). I don't use python3, but the ports are openmaintainer, so you're free to add them.

Applied to the ports in r83061; no point having the variants if they don't work. This isn't in a form suitable for sending upstream since it's mostly just running 2to3 in the portfile. It looks like upstream is planning on solving this by dropping python 2.5 compatibility and using a common subset of python that works in versions 3.x and 2.6+.
