Ack (on the latter).

This sounds reasonable (mire the altree than the perl option, IMO),
but before I could play around with it ...

... I couldn't reproduce the bug (in 3 tries), rebuilding your scenario
manually (i.e.: wheezy chroot, install altree, dist-upgrade).
libpdl-stats-perl gets removed for me, "Processing triggers for pdl"
never shows up. Excerpts from the dist-upgrade (full log attached):

Preparing to replace pdl 1:2.4.11-4 (using .../pdl_1%3a2.007-3_amd64.deb) ...
Unpacking replacement pdl ...
Preparing to replace perl 5.14.2-21+deb7u2 (using .../perl_5.20.1-3_amd64.deb) ...
Unpacking replacement perl ...
Removing libpdl-stats-perl ...
Preparing to replace perl-base 5.14.2-21+deb7u2 (using .../perl-base_5.20.1-3_amd64.deb) ...
Unpacking replacement perl-base ...
Setting up perl-base (5.20.1-3) ...
Preparing to replace perl-modules 5.14.2-21+deb7u2 (using .../perl-modules_5.20.1-3_all.deb) ...
Unpacking replacement perl-modules ...
[..]
Setting up perl-modules (5.20.1-3) ...
Setting up perl (5.20.1-3) ...
[..]
Setting up pdl (1:2.007-3) ...

So for whatever reason, the order is different for me ...

No idea what this tells us.


Cheers,
