I stumbled upon Luiz Henrique de Figueiredo's treasure trove:

http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/

One of his Lua library being "lalarm", an alarm library for Lua based 
on signal and SIGALRM.

This sounds exactly like what I would need, right?

I would love to give the above library a spin, however I'm quite at 
loss on how to compile and install it :/

I tried to follow Luiz's instruction at "Installing my Lua Libraries":

http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/install.html

... but without much success so far:

% make
cc -I/usr/local/include -ansi -pedantic -Wall -O2    -c -o lalarm.o 
lalarm.c
cc -o lalarm.so -shared lalarm.o
cc: unrecognized option `-shared'
ld: Undefined symbols:
_main
_lua_call
_lua_error
_lua_gethook
_lua_gethookmask
_lua_gettable

_lua_pushnil
_lua_pushnumber
_lua_pushvalue
_lua_setfield
_lua_sethook
_lua_settable
_lua_tonumber
_lua_type
make: *** [lalarm.so] Error 1

Does anyone has a make file for Mac OS X?

For the record, I'm using lua-5.1-work4 on Mac OS X 10.3.7.

Thanks!
Cheers
