Thanks Peter.

I'm using Python 2.6, but it works at the command line.  The error only
appears in Eclipse as a red cross in the margin.  The exact error msg, as
appears in a floating text caption on mouse over, is as I mentioned

Perhaps it is some issue in PyDev, maybe related to the version of Python
I'm using.

I'm in the process of trying to solve another related import problem, and
wished to resolve this one in the hope that it might shed light on the
other. But as it works beside the error icon appearing, I might just ignore
it and spare the trouble of precise identification of cause.
