The most probable explanation is indeed that apt does not find a solution
since it is incomplete (it does not try to install older versions of
a package when a newer version is available). As long as apt is incomplete
we may always have false positives of this kind.
Anyway, I'll have a look. For that, edos-builddebcheck should have an
option to display the solution in case installability is reported
(I'll open a wishlist bug for that).
Cheers -Ralf.
