--- Comment #3 from Shmerl shtetldik@gmail.com --- Interesting, I'm not sure why it's not working using build-dep. May be it's falling back to Debian's own wine package for this and that is missing something? It can be some confusion of repositories priority potentially, since your source package is called "wine" and Debian's own repo source package is also called "wine".
Not a big deal though, I just install it manually in my local build script.
