It would be really simpler if versionned provides were supported. :)

I agree but it's similar to the problem we did already have with
xdm killed automatically by a bad-written preinst that could not
be changed once installed. The problem here is that all perl modules
depend on perl but in fact depend on a specific version of perl (all
binary modules are alredy installed in a versionned directory ...),
this problem won't appear again with the new perl policy but we can
do very little for the already installed packages. Nevertheless I
send a bug report against netbase (#35236) to ease the transition from
one perl to another perl and this solution (add a use lib line
in programs) can be generalized too all debian-specific 
(or something-specific) perl modules...

Yep there is. The only possible solution is to add versionned conflicts
to the perl dummy package that would consist of a list of ~40 packages, 
but that's not reasonnable.
