Davisp python-spidermonkey

I've gone through what appears to be a lengthy installation process but I still get an error of
Import error: No module named spidermonkey
I've never had to do more than

sudo python setup.py install

before so this has been very much more complex. Forgive the verbosity but the following seems like it might give a clue to someone more knowledgable than I as to what is going on... Any advice (in very simple terms - I'm a rookie at this) would be much appreciated.
