It's me again :) $ /usr/lib/cyrus/cvt_cyrusdb Usage: /usr/lib/cyrus/cvt_cyrusdb [-C altconfig] <old db> <old db backend> <new db> <new db backend> Usable Backends: db3, db3-nosync, flat, skiplist However, cvt_cyrusdb (and the whole cyrus package) is linked against DB4.1. So, what is "db3" doing there? Or was DB3 sucked in statically?
