BDB despite apparent lack of BDB databases

My imapd.conf has no mention of the database formats.  I'm using Debian, and I believe that info is supposed to be in /usr/lib/cyrus/
I don't have that file either because the Debian instructions say to delete that file when you change the database format, putting
the new formats in cyrus-db-types.txt.  That file is
DBENGINE BerkeleyDB5.3
DUPLICATE skiplist
MBOX skiplist
PTS skiplist
QUOTA quotalegacy
SEEN skiplist
SUBS flat
TLS skiplist

The deletion of the .active file is supposed to be a signal to the package machinery to convert database formats and copy the .txt file to the .active file, but that is not happening.  Perhaps because the necessary cyrus utility programs also fail.

I tried copying the .txt file to the .active file by hand, but restarting produces the same log messages as before.  I am letting it run, and the log shows it upgrading the indices in all the folders in the mail spool.  At the end, despite complaints,  cyrmaster (Debian's rename of master) is listening on port 143.

Have you modified your imapd.conf to indicate that the files are skiplist?
It's not enough to convert the files.
