I just went through that a few days ago.  I ended up just answering y to
everything and letting it remove the packages.  I then went back and
used pkg to reinstall the ones it had just removed.  I had thought that
pkg would fix these types of problems, but obviously not.

When I asked here at that time, someone suggested 'pkg check -Ba' to see
if there are pkg problems.  In my case there were some, but fixing them
didn't help the solver problem.
