I would say that is not necessary; the overall topic of this thread is
package management, so we stay within its scope and just start a more
specific sub-thread. It is good that you changed the subject, to make it
more likely to attract Daniel Burrows (the author of aptitude, who does
seem to read this list).

Indeed, there seems to be a problem with aptitude's databases. Please
check what dpkg itself thinks about libperl, i.e.
dpkg -l libperl\* | awk '/^[^D|+]/{print $1,$2,$3}'
I have in the past experimented with mixing apt-get and aptitude; I
never had any problems. There were (and maybe still are) some
differences with respect to handling of automatic installs and the
persistence of scheduled actions that one should be aware of, though.
In recent years I have only used aptitude in interactive mode (ncurses
interface), so I am hesitant to make any strong statements about
aptitude's behavior in command-line mode, and even more hesitant about
apt-get.
My personal philosophy is that I try to keep all packages on my Sid
systems up-to-date, because then I will only have "normal Sid problems",
which are shared by many people, so they will discovered and solved
quickly. With a partially-outdated Sid system, there might be additional
issues (unforeseen by the package managers, who assume their packages
are installed on a current system), and you are more or less alone with
them.

[ snip: Again, a nonsense proposal instead of simply upgrading all the
perl packages. This is not surprising, we have to figure out why
aptitude does not see libperl5.10 as installed. ]
