The libmail-box-perl case hits another issue, filed as #403246 ("sbuild
dependancy resolution fails when b-dep on A | B ; A uninstallable").
See also the discussion in #422879: "As I understand it, that's the
intended upstream behaviour."

libmail-box-perl build-depends on 

 libscalar-list-utils-perl (>= 1.13) | perl (>= 5.8.2-2)

but libscalar-list-utils-perl is only available in sid as a provided
package, so the versioned dependency cannot be satisfied at all and
sbuild gives up without considering the other option.

As for svk, I'm able to build 2.0.1-1 with current sid and a patched
sbuild. What's the error message you're getting?

Cheers,
