'require' issue

[Mike Nelson <mikestar1313@...>]

My first post to the list (I've been lurking for a few months)

I built the rc7 interpreter from source on mingw for  Windows Vista 32-bit.
require works perfectly for Lua scripts, but on attempting require 
"lfs", I get this error:

C:\Lua52beta-rc7\bin\lua52: multiple Lua VMs detected
stack traceback:
    [C]: in ?
    [C]: in function 'require'
    test.lua:4: in main chunk
    [C]: in ?
>Exit code: 1

 I made sure that this is the Lua 5.2-compatible version.
This file works perfectly with the prebuilt  rc5 inerpreter from Lua for 
Windows.

I can't tell if this is a bug or if I made a mistake in building. I 
haven't used makefiles since college (I'm now retired),
so I could easily be doing something wrong.  Any help would be much 
appreciated.
