That would be great :)

In the meantime, I tried to cargo cult the build, but to no eval:

% cd luasocket-2.0-beta3
% lub
(info) compile: 'gcc -O2 -fno-common -c -o auxiliar.o auxiliar.c'
(info) compile: 'gcc -O2 -fno-common -c -o buffer.o buffer.c'

auxiliar.o buffer.o except.o inet.o io.o luasocket.o mime.o options.o 
select.o tcp.o timeout.o udp.o usocket.o'

Even though it seems to build properly, I get "symbol `_luaopen_socket' 
not found" when trying "require( 'socket' )":

lua: Example.lua:200: error loading package `socket' (symbol 
`_luaopen_socket' not found)
stack traceback:
        [C]: in function `require'
        Example.lua:200: in main chunk
        [C]: ?

I tried to rename the luasocket.c "luaopen_socket" function to 
"_luaopen_socket" but that didn't help.

In any case, this was not an entire waste of time as I took this 
opportunity to build a diminutive build system named "lub" (aka "Lua 
build"):

http://dev.alt.textdrive.com/file/lu/lub.lua

"lub" expects a "lubfile" which describe what to build. Here is one for 
Luiz's lalarm library:

{
        [ "module.name" ] = "alarm",
        [ "object.names" ] = { "lalarm" }
}

I managed to compile, build and use several of Luiz's libraries that 
way. As well as Kepler's LuaFileSystem.

Thanks to Mike Pall for unlocking the door to the kingdom :)

Cheers
