libdb does not exist anywhere but more recent versions of Linux.  That 
link does not exist on older, non-RHL Linux's, nor on FreeBSD, nor on 
Solaris.  The proposed configure change would actually make us much 
-less- portable, unfortunately.

The ideal is somewhat close to what a LJ poster proposed:
* include from $include_dir/$db_version
* link from libdb-$db_version
* provide pkgconfig info that gives us precise location information

That's how, eg. glib/gtk+ 1.x can co-exist with glib/gtk+ 2.x.

But we lack a time machine to make this happen :/
