excerpt from Thread.pm doc:
CAVEAT

The Thread extension requires Perl to be built in a particular way to enable the older 5.005 threading model. Just to confuse matters, there is an alternate threading model known as "ithreads" that does NOT support this extension. If you are using a binary distribution such as ActivePerl that is built with ithreads support, this extension CANNOT be used.

You got some version etc checking to do, try perl -V
