Unable to build Apache::Scoreboard 0.10 with 5.6.0/1.3.17/1.25/RH 6.2

[Mike Janson <ma...@quios.net>]

I am encountering the following problem when attempting to
install Apache::Scoreboard 0.10 on a fresh Red Hat 6.2 install
(2.2.14-5.0 kernel) with Perl 5.6.0, Apache 1.3.17, and mod_perl 1.25
(all installed from source, not the RH RPMs):

I have seen posts about similar types of problems folks have experienced
in the past, but have verified the above version numbers of related installs,
and am under the impression this should work.  Can anyone help shed some light
on this?
