AIUI PYTHON_TARGETS determines which python version extension modules are installed for. If you don't set PYTHON_TARGETS explicitly, portage sets it according to the versions you have installed. -- Neil Bothwick Plagarism prohibited.

But doesn't the PYTHON_TARGETS with which a package is built create a strict dependency on those pythons?

All I did was, after --sync and rebuild but before --depclean, I removed the line from world. I think before digging further, I should eliminate any guessing about what PYTHON_TARGETS is actually set to.

Why did portage remove my python-2.5? Yes, after every world update. I'm not sure why python-3.5 was removed. Before you set PYTHON_TARGETS in make.conf, had you run an `emerge --sync' in a while? It's possible the default PYTHON_TARGETS from your profile did not include python-3.5, so --depclean would have removed it. Alec
