I haven't tested this in depth - so I'm not sure if it works so easily - 
I remember there are two search paths in Lua, one for .lua files and one 
for compiled files, and I can't remember right now if I added support 
for the compiled file path (I have a hunch that I didn't, because I 
wasn't sure how to get it to work cleanly with the .so vs .dll file name 
stuff...).  I also can't remember if I added the require path hooks for 
plain .lua packages to both the Lua loader and the [luax] object.

So, it might require (sorry for the pun..) some fiddling to get it to 
work, maybe modifications/recompilation of the C part of pdlua, etc - 
patches welcome, but I'll get around to testing it thoroughly soon, and 
probably rewrite that part of the code completely (if I remember 
correctly I used Lua's C api when using Lua scripting would be easier to 
maintain...).

Expect a new release of pdlua when I'm confident that the require stuff 
is all working satisfactorily.
