In order to have the 'reset' LUA_PATH (aka `;;`) work, and for purity reasons(removing /usr paths) we(I) decided to patch the lua interpreters default LUA_PATH. Turns out the interpreters have different defaults and the patch was too coarse. There is smarter patching that can be done via LUA_ROOT. Also luajit doesn't need patching at all since LUA_ROOT is set via the build system.
