Linux shared library for Lua

[xoft]

I need someone who's more experienced in Linux than me.

I'd like to try making MCServer use the Lua library as a shared object, instead of linking it statically. However, I have no idea:
1, How to install the shared library
2, How to find the library's name

I have installed luarocks, which uses Lua and most definitely has the lua shared library somewhere, but how do I find it?

Thanks in advance.
