mirrorselect has not been ported to the new python-r1 eclasses which do the python dependency setting via a python_taget use expand variable. the mirrorselect ebuild has: RESTRICT_PYTHON_ABIS="2.[45] 3.1" the python.eclass is suppose to set the python dependency. In this case restricting it from installing to python-3.1. I'm not sure what to do for this, short of migrating it to the new eclasses.
Maybe use python_convert_shebangs to hardcode the shebang to the latest supported version that's installed? I'm not sure why anyone would set python3.1 as default interpreter these days though, when they could use python3.2 instead.
python.eclass doesn't like it when you have the eselected python interpreter in RESTRICT_PYTHON_ABIS. This could probably be fixed in the eclass, but we are basically abandoning the entire eclass anyway.
Well, after chatting with some others. This is something that you should not be doing anyway. Don't set python-3.1 as the active version. Upstream support has been discontinued, and there are a number of discrepancies which make it incompatible with 2.7, 3.2 and future versions. Which is why I added the 3.1 restriction in the first place. Testing showed that the some code was not compatible with 3.1 and it was not worth the effort to code around it for a dying python version. The default active versions are py2=>2.7 and py3=>3.2, both of which are stable keyworded. I am also going to wait till the next release before migrating the ebuild to the new python eclasses. I did some extensive changes to the code so it is liable to have a couple bugs to fix, so it will likely be soon, after some more user testing.
