Find the directory that you installed pycairo to.

Now verify this is in your python path:

$ python
>>> import sys
>>> print "\n".join(sys.path)

If it isn't, then either fix your python installation, or work around it
in your script via something like:

import sys, os.path
sys.path.insert(
    0, os.path.realpath("/my/path/here/"))
import cairo
