ClamAV apparently not being called

[mikea]

To the best of my knowledge I haven't made any changes that would
stop ClamAV from being called, or to stop it from being found.

It was working up to about a week ago.

I've rummaged through the archives and lots of posts to the list,
but haven't found anything that rings a bell.

This is an old, but functional installation of MailScanner-4.20-1,
SpamAssassin version 2.50, and ClamAV version 0.65.

clamscan finds infected files when I run it manually. SpamAssassin
runs just fine and *is* called by MailScanner. The only problem
I have, aside from needing more resources as always, is that
MailScanner appears not to be calling ClamAV.

A typescript of the output of MailScanner with Debug on for
MailScanner and SpamAssassin is available.
