Ouch.  Is this specific to RHEL/CentOS/SL 6?  Was it the case with 5 as well?

It seems like we need a distro-specific note here (and maybe a
separate RPM for RHEL6 and offshoots?), so trying to scope out what is
affected.

The only issue here (and why I backed Erik's initial decision on this)
was that we don't necessarily want to flood the requirements list with
a set of dependencies which are packaged with core Perl.  If Red Hat
is doing something crazy with packaging Perl, this is a problem for
Red Hat users, not for all users.  Consequently it makes more sense to
put in a note saying "If you are running x, perl doesn't come with y
so you have to install it separately" rather than just saying "you
need y."

I'm also in process of reviewing whether this might be a stale
dependency.  I will let you know.
