AnyEvent not working in Windows 2000

Hello I installed Net::RabbitFoot (that uses AnyEvent) on Windows 2000
(with a Strawberyperl installation) and it doesn't work, it gives this
error:

Can't use string ("") as a subroutine ref while "strict refs" in use at C:/straw
berry/perl/site/lib/Coro/AnyEvent.pm line 147.

The same scripts in Ubuntu Linux work fine.

How can I fix it to make it work?

Thanks,

Javier.
