 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
 }}}
