  Let's say that you have two Lua versions instaled on the same 
system in different folders.

  Both will look for LUA_PATH and LUA_CPATH. Where we are going to 
install modules for the two different versions? (assuming the modules 
are not compatible of course).

  Since the contants of those enviroment variables can be very long 
I think that the "LUA_5_1_PATH" is a simple solution.

  The solution that we were considering for another project is to 
dynamically set the environment variables during application 
initialization. The application will know which version is running so 
just configuring LUA_PATH will be enough. But this may not be a good 
solution for everyone.
