I haven't installed MySQL using Marc's package for a while. It should work. Marc's site does not include the latest MySQL package. I understand that similar Mac OS X packages will be available from the official MySQL site, in the near future.
With that in mind, you should be able to get the package from Marc's site to work with CFMX & ViennaSQL.
To use the jar file you mentioned, you need to install it where it can be found by ViennaSQL, CFMX, or any other Java program -- copy the JDBC driver jar file to:
Then, setup the appropriate connection for ViennaSQL as in Part 4 of this series.
As far as testing the MySQL install, I never got the Test procedures to work (though I did not spend much time trying).
