Thank you!  That took care of that weird error message, but I think I
now have a permissions problem.

Or maybe it's not a permissions problem:

mythzmserver says:

The last 2 blocks occurred with any operation on the frontend.  I then
changed the mythzoneminder address from localhost to 192.168.200.9 and
I now get this:

Failed to get mysql row
Failed to shmget for monitor: 2

But now at least I see the ZoneMinder Console and I see the one camera
listed.  The "Source" (/dev/video0(0)) is marked as [S] (Stopped) even
though on the web browser it says Capturing at 17.48MB/s.  The
"Function" (Monitor) is marked as [R] (Running).  The top field says
"Running" or "Stopped" depending on what I select with the web browser.

Show Live View only shows the test pattern.  Clicking on the name of the
camera in the web browser brings on a live view so I know the zoneminder
part works.

There are apparently some compatibility problems with the database.  I
created it with /usr/share/zoneminder/db/zm_create.sql
and I see no errors when running it from the web browser.

Has anyone seen this before? Any possible solutions or work-arounds?

Thank you Paul for quickly solving the first issue.
