Most ebuilds in the gentoo repo are either using pkg-config, or
already have hacks/patches applied. Perhaps if this idea were offered
earlier in the year, it might have actually helped.
The versioned libdir subdirectory seems like a nice idea for people
building stuff against lua outside of ebuilds. Jonathan's proposal
could be treated as an enhancement at a later date.
