Spot, Jesse Keating, and I just had a call to try to work these issues
out.  Spot is going to continue to look into what needs to be done to
split out perl-devel.  Unfortunately, it looks like perl may be too
tangled to allow us to make this split clean and still include things
that are considered 'core' perl by most people - such as CPAN, for
instance.  I would argue that CPAN *is* a 'devel' utility, but most
people would expect it to be installed on a system whenever perl is,
which is fair.

If he can get things in shape by tomorrow, we may be able to keep
perl-devel split out, perhaps with a 'Requires: perl-devel' in F7's perl
and a 'Provides: perl-devel' in the perl for previous releases to keep
modules building and working in both cases with the same spec file.

However, we should work towards removing the Requires: perl-devel from
perl at some point in the future, since that way it's not much better
than just having everything in perl.

If he can't get things working in relatively short order, we will look
at just rolling perl-devel back into perl and adding a Provides:
perl-devel.  We'll consider the fact that perl isn't split out into
perl-devel as a bug to be fixed in Fedora 8.

Thanks for your patience.
