It would be possible if both used the same versioning. Looks like base on my desktop (10.3) is not using versioning, so if the version map is provided by openssl we could in theory just use their version map when building base openssl. That is actually the far easier problem to solve (using upstream-maintained version map vs trying to maintain a local version map that has to be updated manually whenever upstream changes). -- John Baldwin
