Hi folks: I've recently migrated one of my production servers (bad Jason!) from WBEL to CentOS 3.3 using Donavan's instructions in the FAQ (http://www.centos.org/modules/smartfaq/faq.php?faqid=19). While it was as painless as the document suggests, I've run into problems with postgrey (a postfix greylisting daemon) on my server. Whenever I try to start postgrey, I get the following error (trimmed from maillog): ERROR: can't create DB environment: No such file or directory A little research led me to find the error was caused by a call to BerkeleyDB::Env->new() in postgrey. I can recreate it in a simple Perl one-liner: perl -e 'use BerkeleyDB; my $db = BerkeleyDB::Env->new() or die "blah";' This leads me to believe that something is wrong with db4, so I upgraded (--force) to the CentOS db4 package. Unfortunately, this had no effect. Speaking with Dag in IRC a couple nights back, he believes my only recourse may be to "pin" my apt sources and attempt to upgrade all of my WBEL-based packages to their CentOS counterparts. I would really like to avoid this; if necessary, I think I'd prefer to try and upgrade from the 3.3 ISO. Anyone have any thoughts or suggestions on this?
