perl5.20

[Mojca Miklavec]

Dear Frank,

first of all, thanks a lot for doing the mass update of the number of
Perl modules.

Do you know how to implement this, possibly together with replaced_by
for 5.8 and 5.10? (If we would implement this, I would suggest to try
to get rid of 5.8 and 5.10 already in the first round.)

I'm annoyed by a bug in 5.10 https://trac.macports.org/ticket/42146
which causes a whole cascade of perl modules to fail and that only
gives false alarms from failed runs on the buildbots when modifying
ports.

That would also be nice. But we would need to make sure to revbump all
such ports anyway.

Yes, that's what I said.

The digest-sha1 works for me, pdl takes a bit longer, but eventually
fails for me as well.

The first one is
    my ( $sym, %hash ) = split chr(0), $txt;
and the second one is a consequence of the first one failing. I don't
speak Perl well enough to be able to diagnose.

I see that the buildbots failed to compile opengl and wx. OpenGL failed with:

but it works when I build it from source.
