Thanks to all who answered (including offlist).

If I would like to force all ports to become compiled with db48,
I would use "WITH_BDB_VER=48", instead. Understood.

But, is there a way to define something like "use at least db48"
and ignore whatever is specified by the port, except, if the port
specifies a version > db48.

Sorry, that might be a dumb question of mine, but I just want to 
learn more about those knobs.
