ClearCase gives you tremendous control over what can be seen at any
point.  Assuming that you are using dynamic views, the simplest way to
fix this is to use a different view for each platform.  They would
both be able to see the py files (although you could control that with
the configspec)as checked in, but the pyc files would not be checked
in and would automatically be view private.  So with two different
views, each platform would only see its own pyc files.
