Currently, the py-bsddb port will only builds with
the db3, db4 or db41 ports. It is missing support for
building with the db42 port.
Fix: The following patch allows anyone to choose which version
of the Berkley DB to use by defining WITH_DB3, WITH_DB4,
or WITH_BDB_VER when building the port.
NOTE: WITH_DB3 overrides WITH_BDB_VER, while WITH_DB4 does
not override WITH_BDB_VER.
How-To-Repeat: Install databases/db42 and databases/py-bsddbi (db41 installed by default).
Over to maintainer.
