It is similar to what I suggested in the first mail, without "single_":
Set these in /etc/portage/package.use like so:
dev-util/eric python_target_python2_7
(Yes, PYTHON_TARGET expands to USE flags.)
The tricky thing about this, per previous mail, that you need to keep
into account that once you set a target on a Python based package, that
it also needs to be set on its Python based dependencies; which means
that if a certain Python based package is 2.x-only, you'll need to
build its dependencies with 2.x too for it to be able to function.
