[plt-scheme] Trying to define a module requiring swindle.ss

Hi,

When I try to define a module and then require swindle.ss like this:

(module netcheck mzscheme
  
  (require (lib "swindle.ss" "swindle"))

...

)

I get:
module: identifier already imported (from a different source) in: define

It seems there is a definition of module or something inside swindle.ss.
How can I manage to work it out?

Cheers,
