When I tried to run PDFRead on my Mac (after installing all of the dependencies) I get this:
Traceback (most recent call last): File "src/pdfread.py", line 51, in ?
import os, sys, re, subprocess, Image, ImageFilter, ImageChops, optparse, shutil, traceback
ImportError: No module named subprocess
Please check that you are using python 2.4 or later (You can find the current version by running "python -V"). If you're using 2.3 or lower, you can dowload the missing subprocess module
(which was introduced in 2.4), save it as subprocess.py in the same directory as pdfread.py, and try again.
