The mysql errors arise because in prerelease 4, webwork will
automatically try to connect to problem library data in mysql and throw
an error if it can't connect. So, I am afraid the answer is no. What is
needed is mysql running and the database of problem information in
This bug was fixed in late May right after prerelease 4 came out. So,
if you replace your files with the current versions from cvs, then you
don't have to worry about having mysql running. This is only one of the
dozen or so bugs which have been fixed since prerelease 4.
The only downside to using the latest cvs version is that you need to
download the files through cvs (just "cvs up -d" in the two main
directories if it has been done before), and if you have configured
global.conf, you will have to put those changes into the latest version
of global.conf (and possibly check the value of the dvipng arguments
which now live in Constants.pm, to see that they correspond to your
version of dvipng).
