I think this is due to some old dependencies being installed. While technically it's an ebuild bug, upstream doesn't let us know when they break their API (soname doesn't change). And I would rather not try 100 versions by hand to see where the breakage starts. Can you try with "emerge -uDN coinor-cbc" to pull in the latest versions of its dependencies? I think that will solve it.
