apt-file finds 91 packages in sid matching /usr/share/fonts/X11. That's
a bit much.

My point was that this is potentially a much wider issue, not limited to perl.
But concentrating on this specific issue which is clearly RC for jessie:
assuming we don't want to change all the 91 font packages, I see these
possibilities:
a) - make xfonts-traditional 'postinst triggered' survive missing dependencies
- make perl-base+perl-modules+perl Break xfonts-traditional older than that
b) - make perl-base+perl-modules Break: perl (<< 5.20.0~)
- make perl-base+perl-modules+perl Pre-Depend on dpkg (>= 1.17.17)
The second choice is a more generic fix that may benefit other packages
too, assuming those Breaks are the "correct" thing to do.
I'm inclined to do b) but at least the predependency needs a discussion
on -devel too so I'll go there next.
