Now I'm getting the following error when I try to plot something in ipython notebook:
    AttributeError: 'module' object has no attribute 'FigureCanvas'

I've tried using imports to make this work:
    import matplotlib.pyplot as plt
    import numpy as np
    x = np.arange(0, 5, 0.1);
    y = np.sin(x)
    plt.plot(x, y)

but for some reason when I add the --pylab=inline that all the tutorials mention I get the AttributeError I mentioned before. I'm starting to wonder if this is a problem with my machine setup, if I'm missing something else that ipython notebook needs to do inline plotting.

Any help on this would be appreciated -- at this point I'm banging my head against the wall and solution doesn't seem to have surfaced through googling.
