Qemu (and maybe others) won't build with python 3 as default

[guillaumesalagnac]

Installing qemu fails when the default selected python is python 3.1. But if I "port select" python 2.7 instead, then it works fine :

That's not surprising at all. Yes, it's a bug in the qemu port that should be fixed, but it's probably a bug in hundreds of other ports too.

Thanks. Is there something I could do to help ? I'm a very happy user of macports, but I know little about the internals...

Given that you haven't named any specific "others", this is a duplicate of #34471.

[guillaumesalagnac]

indeed. thanks.
