I submitted a patch to split lang/lua51 and lang/lua52 a while ago
and I resumed working on it just yesterday.

I've got both lua packages installed (see file listing for lua 5.2
below) but some (or many?) Lua modules install files to common
directories (e.g. lib or bin). Take a look, for instance, to
databases/lua-tokyocabinet. I'm going to address it by introducing
LUA_DOCDIR and LUA_EXAMPLESDIR and some support mk files like tools.mk.
I remember your email about rocks and I agree that we also need
something like rocks.mk but I've never used this framework and I can't
promise I can code it up while working on this project. Perhaps it's a
good opportunity to switch some packages to rocks framework ...
