I can help with that one: Your compiler command line doesn't specify an 
include directory for the Lua headers, so the rockspec/Makefile will 
only work on machines where the Lua header files are installed in one of 
the standard locations. It fails on machines running e.g. Debian/Ubuntu 
which support multiple Lua versions by using include directories like 
`/usr/include/lua5.1`. LuaRocks provides the `LUA_INCDIR` variable which 
you can pass from the rockspec to your Makefile for setting the proper 
include directory for the Lua header files ...
