A general loadlib request: Lua 5.1 has an OS-independent wrapper for DL 
calls. Since I'm in the process of integrating Bruno Haible's av_call 
into 5.1, I would need the Lua dl functions split up into the dl access 
and the symbol lookup part.

What I already had for Lua 4 was code to do the following
dl=dlopen("/usr/lib/libm.so")
ffcall(dl.sin, "dD", 3.14159) --
I'd like to be able to use the wrappers from Lua 5.1 to do the same, 
i.e. dlopen and the gettable metatable method for a dl object. I could 
modify the relevant pieces myself, but right now don't have a Mac nor a 
Windows box to test. Also, would like to clarify the design issues with 
you gentle folks in Rio...
