Me too.  The binary rpm in FC4 and FC5 was built before we had
javadoc, so the error wasn't noticed then.

It's odd that most things work without, though.

Some packages check for the existence of certain classes and disable
bits of themselves if they're not found.  It's possible that
avalon-framework has such checks, but is missing some build dependency
that forces the necessary class to be installed at build time.

Do you have any idea how to fix the javadoc thing?  If so, I can
rebuild avalon-framework and see if the class you need appears.
