I've upgraded more than a dozen machines from WBEL to CentOS-3 ... and I
haven't had any problems.  I don't have the perl module "BerkeleyDB.pm"
on any of my machines though...nor is it on my CentOS-4beta "Full
Install" machine that I use as a build machine for CentOS-4beta.  What
package installs it?
