The packages in question are arch: all, so have never been seen by the
Debian sbuild.

I agree that it's a bug that warrants fixing, but I also think it's wrong to
ship two copies of the perl module, at two different versions, resulting in
who-knows-what subtle behavior changes based on which packages are

So fixing sbuild IMHO only fixes one of the bugs that have been brought to
light here.
