Bug#550825: Unable to upgrade perl (did I hit #502455?)

[Amaya]

Package: perl-modules
Version: 5.10.1-5
Severity: serious

Dear Perl team,

I have been hit by a bug that has my dpkg screaming in pain. I can't
install or remove anything anymore. I have been investigating a bit, but
I don't know how to proceed from here, a bit of advice would be most
welcome.

You might want to run `apt-get -f install' to correct these.
The following packages have unmet dependencies:
  perl-modules: Depends: perl (>= 5.10.1-1) but 5.10.0-25 is installed
E: Unmet dependencies. Try using -f.
~-root at io>dpkg --configure -a
dpkg: dependency problems prevent configuration of perl-modules:
 perl-modules depends on perl (>= 5.10.1-1); however:
  Version of perl on system is 5.10.0-25.
dpkg: error processing perl-modules (--configure):

After this operation, 160kB disk space will be freed.
Do you want to continue [Y/n]?
E: Internal Error, Could not perform immediate configuration (1) on perl-modules

If I try to manuall install all perl packages, same result is obtained.
Thanks for your time, and for any time. Please reassing (dpkg?) if you see fit.
