[Zope] installing ReportLabs

I installed the report labs product per the instructions included with the product in Zope's .../lib/python/Shared directory with the interface routine rlzope installed in the Extensions directory. When try to install the External Method it fails because it cannot import Paragraph from Shared.reportlab.platypus.paragrah. A path problem of some sort, but it's not clear where the problem lies. ANyone else encountered this one? -dra
