Oh yes it sure did help. It took me a while to get apache compiled (I'm a bit
addicted to the simplicity of RPM) but after I got everything figured out it
works great.

I totally disabled DSO just to be on the safe side.

Everything is running very smoothly now - if anyone is interested in how I used
ht://dig and mod_perl on Apache to build an internal search engine, I'd be happy
to describe my adventure. Is this the kind of stuff a Spug (or espug) meeting
is made of?
