If you are working with Apache on a PC under Windows, may I ask where you downloaded it? I went to the site referenced in Practical mod_perl, which pointed to three sites. It was not immediately obvious from the first two how to download Apache, MySql, etc, while it was fairly straightforward from Zangweb.

Thank you for your time. I no longer have access to a Unix box, and am trying to master this (for me) new skill set.

Revised: Thanks, almut, for reminding me that the hardware is not the OS...
