Having just spent quite a bit of time wrestling with mod_perl, I might have 
some insight into this.

the mod_perl sipped with CentOS is 1.99, but with a subversion BEFORE a major 
API shift that was standardized for mod_perl 2.0.  Your libapreq2-2.02 is 
probably trying to utilize the new API and running into problems.

You could either:
A) build or acquire RPMs for a true mod_perl 2.0 environment (I didn't have 
much luck getting my target app to run when doing this, but that could have 
been my particular app), or
B) wait for CentOS 5 and use that (if you are comfortable with using the 
initial release).

I would suggest using CentOS 5 if you require the features of mod_perl 2.0 and 
above.  If something has a problem, it will most likely be fixed by Redhat, 
so you aren't responsible for tracking down small inconsistencies with self 
installed packages.

If you have more problems with this, you will probably be better off posting 
to the CentOS users list, since this is almost definitely a conflict with a 
self installed package and not a core component failure/bug.
