Peculiar. The 2.0 tag branch of utils.py has a try block around that statement

eg

try:
     _isFSD = not __loader__
     .......
     .......
except:
     #do something else

I notice that you appear to have 
/home/metroviewer/Desktop/reportlab_2_0/reportlab/ in one place and 
/usr/local/lib/python2.4/site-packages/reportlab/ in another so the older 
version of reportlab may be buggy.

A way round this (and a check) would be to try setting this in your environment 
before running the test


export PYTHON=/home/metroviewer/Desktop/reportlab_2_0
python /home/metroviewer/Desktop/reportlab_2_0/reportlab/test/runAll.py
