If you've been getting errors like this:
File "PIL\ImageFont.pyc", line ---, in load_path IOError: cannot find font file
The fix is to simply copy the files helvetica-10.pil, helvB08.pil, helvetica-10.png and helvB08.png into the "dist" directory.
It may also be needed to add current path in the load_path() function in ImageFont.py (otherwise it searches in sys.path directories only).
for dir in sys.path+['.'] instead of for dir in sys.path
