>=app-crypt/xca-0.9.1 contains dependecny with dev-libs/openssl[-bindist] added in bug 350480 According to xca Changelog version 0.9.1 "Support building with EC disabled". Overload ebuild with removed [-bindist] compile without any problem. Because xca depend on [-bindist] and openssh depends on [bindist=] now I can't have them both. Maybe some warning should by added.
Added app-crypt/xca-0.9.3-r1, added bindist USE flag to match the one of openssl, so changing USE will rebuild both packages, as this package lacks the explicit enable/disable the EC support. Thanks!
