in posix.lua there's this line:
if _VERSION == "Lua 5.1" then bit = require "bit" else bit = require "bit32" end

Thus, for lua 5.1, the package requires a 'bit' operations. aur/luabitop seems to work.

To test the issue create a lua file with:

Please report this upstream. Here are a few links for reporting bugs for Lua:

This is NOT an upstream bug (especially not one to Lua itself.) This gets down to the fact that Lua 5.1 doesn't have bit operations built in and 5.2 does. luaposix depends on them. To that fact, it checks for the existence of bit32 (for Lua 5.2) and falls back to a community package "bit". So in all, luaposix requires either luabitop from AUR or Lua 5.2. Thus, luabitop either needs to be promoted to community, or luaposix should be pushed to AUR so it can be properly depend on luabitop.
