Pypilot compass calibration getting lost

[drbarritt]

Hi Sean, I think I may have found the problem. I stopped pypilot and ran pypilot_boatimu. I got error messages about module 'scipy' not loaded. So I did a full update on my Pi and then installed scipy. I now get a different message when I run boatimu:
pi@openplotter:~ $ pypilot_boatimu

What is lib77blas.so.3? The calibration process does not seem to work at all now.
