Mmm. Funnily enough... Derived categories might solve this one. A while
ago I suggested someone implement something for the ERepository family
looking like:

format = derived_ebuild
derived_from_repository = gentoo
derived_categories = \
    sys-devel -> cross-blah-devel
    sys-libs -> cross-blah-libs

which would avoid the need for symlinks.

Yeah, it's not a bad idea, although the implementation has a few minor
deficiencies that could easily have been corrected had it gone through
the GLEP process. Mostly we don't support it in Paludis because I hate
writing code that deals with XML...
