Hi Ed,

You can at do this to test if a module is installed:

try:
     import SomeModule
except ImportError:
     print 'SomeModule is not installed!'

I'm not sure about the part regarding the module installation. I guess 
you would replace the print statement above with some code to install 
the module.

HTH,

Bill
