Currently yes, but I consider this a bug. The patched code already runs
in a loop to check for all alternatives, but it currently fails, if it
can't satisfy a versioned dependency.

sbuild[1301]: foreach $d ($dep, @{$dep->{'Alternatives'}}) {

Without the 'next', $installable is set, even if it's not installable.

sbuild[1325]: $installable = $name if !$installable;
