Nope.  I don't believe you can do that today (at least not without some
build-time gymnastics), and I have no plans to support that.  For one thing,
you'd have to compile and link bsddmodule.c twice.  To allow multiple
versions to be loaded into the interpreter you'd also have to name them
differently.  This would require source code changes to keep global symbols
(at least the module init functions) from clashing.

Thanks, I'll add that.  I also notice that /usr/local/BerkeleyDB.4.0 is the
default install directory for the 4.0 source.
