The more I look at what's on NetBSD the more I think this is Berkeley DB
version 1, it's just that the headers aren't in a db1 subdir. I think
the check should be for gdbm/ndbm.h first, then ndbm.h, then db.h, then
db1/ndbm.h. While this doesn't cater for the situation where a vendor
supplied ndbm has been replaced by Berkeley DB version 1, I think it's
reasonable for the installer to give configure the path if they're unhappy
with the vendor version.
