Are there any other builds of Lua that have this functionality built
in. Like LuaX, ect...

That means I have to maintain the Lua source for my modified version.
Has any talk occurred about adding the setenv() call to the official
release? Is there any tutorial or example on how to add/modify Lua
with this added functionality? I have browsed the Lua wiki and didn't
see any articles about tweaking Lua itself. I know there are the
"Power Patches", just looking for some simpler modification so I can
get my feet wet.

That is an idea. I kinda like that. Is there a way to find out what
platform your script is running on?
For example::
if (OS == "linux") then
   -- Do some linux specific output
   ...
else
  -- Do some Windows specific output
   ...
end

Thanks for your help.
