No, it wasn't compiled thusly.

monit is running as root:

address@hidden:/etc/monit$ sudo /usr/sbin/monit -vI -c /etc/monit/mon
itrc

It shows this line:
system statistic error -- cannot get cpu count: Success
(That is supposed to be the bug that was fixed but it is reporting it
as an error here)

and then this one:

monit: Debug: Adding credentials for user 'jenny'.
But this is just that user jenny with password xxxx is allowed to
access the web page as stated in the monitrc file.

Thanks for the continued help.  I'd love to get monit running again,
it's an invaluable admin tool.
