That's too complex to handle automatically. Luckily, in R overlay, such
packages are less than 5%. An ebuild generator is based on the
observation that many language-specific packages are trivial to fetch,
compile and install.

No, I don't think it possible as far as I can see... That would be a
strong AI.
