You need to catch up with the rest of this thread, since I think we're
moving towards something more acceptable.

However, in the particular case of Perl, I think it does highlight a
slightly separate issue in that our build process has no concept of
deprecating parts of the OS.

The 'sysclean' target will "accidentally" deal with the Perl issue, but
I don't think it's wrong to have a target remove a module that has been
removed from source since that's what installing the system should
really do if the system has opted to deprecate something.
