The issue with the import is that without the try/except block on any system that requires the "PIL" prefix, it will fail. I'm attaching a zip with a make file, could you unpack it and run it on your system:

/tmp $ unzip pil.zip 
Archive:  pil.zip
   creating: pil/
  inflating: pil/Makefile            
  inflating: pil/t1.py               
  inflating: pil/t2.py               
  inflating: pil/t3.py               
/tmp $ cd pil
/tmp/pil $ make
python t1.py
  Found PIL.Image: <module 'PIL.Image' from '/usr/local/lib/python2.6/site-packages/PIL/Image.pyc'>
python t2.py
  Found Image:<module 'Image' from '/usr/local/lib/python2.6/site-packages/PIL/Image.pyc'>
python t3.py
  Found PIL.Image: <module 'PIL.Image' from '/usr/local/lib/python2.6/site-packages/PIL/Image.pyc'>
  Reimported Image: <module 'Image' from '/usr/local/lib/python2.6/site-packages/PIL/Image.pyc'>
