[Zope] ZMySQLDA 1.1.4 install problems

I'm attempting to install ZMySQDA-1.1.4 on a RedHat 6.2 box with the following configuration; Zope 2.1.6-1 Zope-pcgi 2.1.6-1 Apache 1.3.12-2 Python 1.5.2-13 w/dev MySQL 3.22.32 w/dev MySQL-python 1.4-2 ZMySQLDA compiles fine and python imports ok. When I copy MySQLmodule.so to the products directory and restart Zope, ZMySQLDA does not show up in the Products list. All the above were installed from RPM binaries. I did manage to get ZMySQLDA working on a different machine with some difficulty. I seem to have hit a different stumbling block this time. Any suggestions? David
