I see.  I finally was able to reproduce your problem.  There is indeed
something very wrong with the alpha channel output.  The Mac version allows
to view the alpha channel even if POV-ray does not explicitly outout one.
When activating alpha channel output the whole output is suddenly screwed
up.  Obviously this is not right, so i can confirm this is a bug - alpha
channel output is completely broken.
