As far as I am aware, the ldb lib should be backward compatible, so if
the wing repo packages demand an exact version, then the problem is in
the wing packages.

I would do one of two things, contact whoever maintains the wing repo
and point out the problem and ask if they can fix it, or I would drop
the wing repo and find another option. Either another repo, or compile
Samba myself.
