Some perl release symlinks aren't being maintained

FWIW, the cronjobs that run on the master mirror server are below.

cpan/content is a clone of this repository.
cpan/ is devel/cpanorg-generators for weird historical reasons.

cd cpan; ./bin/update-CPAN-data

cd cpan/content; make update-daily
cd cpan/content; make update-master

cd cpan; bin/update-CPAN-indices
cd cpan; bin/update-CPAN-timestamp
cd cpan; bin/update-CPAN-MIRRORING.FROM > ~/tmp/mf.2 && mv ~/tmp/mf.2 CPAN/MIRRORING.FROM
cd cpan; bin/update-CPAN-RECENT
cd cpan; bin/perl-label.sh

(plus a few related to the mirrors list).
