The dependency should currently probably look like: <dev-lang/lua-5.2:= On the other hand, since they decide to stay with lua-5.1 for some time, could you possibly introduce the luajit USE flag, as seen in the example on https://hackage.haskell.org/package/hslua ?
This is what I came up with (should work with lua:0 and tested with luajit:2, lua:1 needs some more work though): https://gitweb.gentoo.org/dev/dev-zero.git/tree/dev-haskell/hslua/hslua-0.4.1.ebuild

What is the more general plan to move to slotted lua in gentoo? Unmask slotted and mask/delete unslotted at some point?

For this we will have to add the lua5.1 include dir and library because hslua does not expect it to be slotted. luajit:1 is not a problem since they explicitly add -lluajit-5.1 in case '-fluajit' is set. > > > https://gitweb.gentoo.org/dev/dev-zero.git/tree/dev-haskell/hslua/hslua-0.4.1.ebuild > > s/EROOT/EPREFIX/ > > We use > https://github.com/gentoo-haskell/gentoo-haskell/blob/master/dev-haskell/ > hslua/hslua-0.4.1.ebuild in overlay for a while. > > Your change looks better than ebuild was.

I have to test it again with portage, but '<dev-lang/lua-5.2:=' should work. If lua-5.1:1 gets unmasked, it will block lua-5.1:0, since lua-5.1:1 still satisfies the dependency, portage should schedule a rebuild of hslua. > > What is the more general plan to move to slotted lua in gentoo? > Unmask slotted and mask/delete unslotted at some point? Not necessary. I was able to switch from unslotted to slotted without any problems. But packages must never rely on the result of 'eselect lua' but explicitly use the latest-and-greatest they depend on.
