The ebuild is missing python_check_deps() function entirely. Furthermore, it is using two incompatible python_gen_any_dep() calls. python_gen_any_dep must be called exactly once for a given USE flag combination.
Plus, it's also implicitly depending on SCons which makes it even a greater horror of a package.
Here's how to fix it: https://dev.gentoo.org/~mgorny/python-guide/buildsys.html#build-time-use-with-extra-dependencies Note that I've stripped stuff irrelevant to the example, so you can't copy-paste it all.
