[Zope] How to get reportlab running and integrated with Zope

Hi all, I have downloaded Reportlab to my linux box and am trying to go through the install procedure. I un-tarred into /usr/local/Zope/lib/python/Products making the reportlab product underneath. This looks good in Zope ... (shows up as product under management screen) However running the test script (testpdfgen.py) under ...reportlab/pdfgen/test/testpdfgen.py gives me a module not found error when it tries to import reportlab.pdfgen. Any clues as to what I haven't set up? Anyone tried this yet? lost in Zen Dale
