compiling poslib to cgilua

[Pablo Saldo <ec4pas@...>]

I tried to compile poslib to use in cgi-lua. poslib doen't create a shared
lib, so I've donne it myself, using ld, the same way is said in lua
INSTALL. But I still have undefine references. 

libposlib.so: undefined symbol: __cmpdi2

Any help? What I really need is only the dir and getcwd functions, whose I
find necessary in cgilua.
