Ports needing revbump after perl5 update to 5.12.3

[ak.ml@…]

A few ports have installed perl modules and were not revbumped since #76604. They need either a revbump or to be recompiled in order to work with perl 5.12.3.

dpkg
libproxy
rpm52

The other rpm* ports might need a revbump as well: rpm, rpm45, rpm50, rpm51.

For those who want to check their system, here's a basic command to list the packages which have files installed in 5.8.9 directories:

$ find \
    '/opt/local/lib/perl5/5.8.9' \
    '/opt/local/lib/perl5/site_perl/5.8.9' \
    '/opt/local/lib/perl5/vendor_perl/5.8.9' \
    -type f \
-print0 \
| xargs -0 port provides \
| sed -e 's,^.* is provided by: ,,;' \
| sort \
| uniq
