I eventually got most things back by removing the site-perl version of
Errno.pm (installed by CPAN sometime in the past, I think.)  There was
another, more recent version which was apparently found automatically,
allowing things to proceed.  I have also removed a bunch of other things
that were in site-perl, especially everything I could replace with a version
from portage.

I have now been able to run 'perl-cleaner reallyall', and have rebuilt perl
both with and without the ithreads USE-flag (see separate thread).  So I
suppose I'm now in good shape. CPAN also works, though I'm a bit reluctant
to use it since that's how I got in this mess in the first place.  I'd
rather rely on portage to keep things current and consistent.   Hmmmm.
Does anyone know how to run CPAN in a cron job, just enough to run the 'r'
command?  I do that with portage to tell me when I have to worry about
revdep or depclean.
