AttributeError: 'module' object has no attribute 'ANTIALIAS_FAST'

I worked around this by modifying /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/cairosvg/surface/init.py and adding the following after the import statements

cairo.ANTIALIAS_FAST = cairo.ANTIALIAS_NONE
cairo.ANTIALIAS_GOOD = cairo.ANTIALIAS_SUBPIXEL
cairo.ANTIALIAS_BEST = cairo.ANTIALIAS_SUBPIXEL
