building from source with libc++

[db]

I use 10.8 (don't need/don't want to upgrade) and stumbled upon a couple of ports that require libc++.

So I gave building from source a try in a vm following these instructions and soon encountered a couple of problems with python2_select (needed base updated) and xorg-libX11 (attached config.log), which is working fine in another system with same versions.

Are there any caveats when always buildling from source in MP?

Should I file a ticket for xorg-libX11?
