First, apologies for the bump, but this is near the top of mod_perl on google atm, and I actually know how to do this.
You need to get strawberry perl 5.10 OR 5.12. I have not been able to find the mod_perl.so files compatible with 5.14+, but that's another issue.
next; follow the instructions *to the letter* in this thread which details how to mod_perl strawberry, including links to the relevant repositories in the strawberry namespace. The testweb directory has an example http conf which I testify works if you adjust properly.
I've deployed this exact setup on both xampp and plain apache in win 2008, r2 and plain Windows 7. It's possible but very easy to make a mistake.
