luckily we have added annotateException which should allow us to modify the 
existing exception and provide some more information

To the OP you could try changing

raise RuntimeError('Imaging Library not available, unable to import bitmaps only 
jpegs')

into

annotateException('\nImaging Library not available, unable to import bitmaps 
only jpegs')

and see if that helps to get more information.
