Nevermind, SuSE 9.1 has been my development system for the better part
of 2004. I'd have know if it hadn't worked. :-)

OK.

Right. But SuSE 9.2, just like 9.1, has a "db40" RPM with BerkeleyDB
4.0, which will continue to work without removing the environment.

When doing an upgrade from 9.1 to 9.2, YaST would leave the DB versions
alone, as SuSE have separate packages for the Berkeley DB minor releases
on either SUSE LINUX release - just make sure YaST doesn't deinstall db40.
