You should be using repoman_settings instead of portage.settings.

Considering the later use, you don't need PackagesSystemSet set here,
just use a set. And use atom.cp instead of the atoms.

Use portage.eapi for the line above. You may have to add a new function
to portage.eapi.

As these regex are used frequently, they should be compiled using
re.compile.

I'd make needed_unpack_depends[mykey] a set. Then you can just add()
instead of checking and appending.

Use "if atoms and buildtime:" here.

Use the existing catpkg here.

Maybe you could remove the entries from the archive_formats variable
once you know if they are in the system set.
