Great, except that there's little control in the linker for what you
get linked against.  Berkeley DB library tends to like to crash if
you compiled for one API and then change to a newer version of the
library at link time that has a different API.

If you have a method to control what library Xastir will link
against when you run it, then you should be safe.  Because I didn't
have (or didn't know of) such a method with Linux, I added the
run-time code to disable use of the BDB library if this problem is
detected, saving Xastir from a nasty crash.
