I would guess you have not installed PIL, the Python Imaging Library, 
which ReportLab uses.

To run a python script, like "test_pdfgen_general.py", at the command 
line type:

python test_pdfgen_general.py

(assuming python is on the path, and example.py is in the current directory)

In general there are two sorts of python files, scripts which you run 
(like test_pdfgen_general.py) and library modules you import.
