how do I tell zope which python to use. and add the zmysqlda to it? The script "start" controls which Python is used. The environment variable "PYTHONHOME" (defined in "start") controls where the Python infrastructure is searched for.

You can use the environment variable "PYTHONPATH" to let Python look at additional places for modules and packages. PYTHONPATH is a colon separated list of directories. Alternatively, you can make appropriate symbolic links to the external components (usually in "<zope_dir>/lib/python". Dieter
