I'm not sure I can point out the right error, but
 - I don't think you need to link against liblua for either platform (and a possible problem is your module getting linked to two separate copies of Lua)
 - for OS X, you'll need to link with -undefined dynamic_lookup
 - I don't think you need -ldl any more on OS X (What version is it?)
 - I think you can use -fPIC on OS X
