oops, the markup mangled the diff.. should be rather clear though :D

Thanks for the patch. My OS (Arch Linux) has no "lua5.1" package though, so I've edited the makefile to use "lua" and fall back on "lua5.1" if "lua" is not found.

Oh ok.. I suppose ununtu is doing it wrong then :D And also it won't work anymore as soon as lua5.2 comes along. Maybe there's a generic way to handle this.

On another note though: I also had to add the line

+ $(INSTALL) -d -m755 $(INSTALL_CMOD)/
