Right, I see.

I think the default of the stock lua (from lua.org) is reasonable for stock lua
since, if you're compiling Lua yourself, then you're quite likely to install it
in /usr/local and quite unlikely to install anything Lua-related from distro
packages. OTOH, when you get packages from a distribution, it makes a lot of
sense to have them in /usr and keep /usr/local for local stuff; actually I think
it's what the FHS says.

Well, it is my opinion that altering the settings this way is the right thing to
do for a distro, but I can see your point. (And since I've never seriously used
anything else than Debian, I admit my opinion is probably biased.)

Setting LUA_PATH works like a charm. Thanks for the suggestion, I completely
forgot it.
