It may be on your system, but does RPM know it's there? Did you use
rpm to install interbase in opt? If so, does rpm -q --filesbypkg
interbase or whatever show this file? It's not what's on your system
that matters to rpm, it's HOW it got there. This is the root of your
evil I suspect.

Sounds like it's missing an entry in the requires line then.

Just because it installs fine, doesn't mean its not busted :-P

Yum does dependency checking of its own, which is a good thing in this
case, because technically with your rpms, I don't have to have
interbase installed to use php-interbase, which will quite possibly
lead to breakage.

I believe so, yes.
