I appologize, then. This, however, made me think you were:
'Now what? "Try simple commands"? Like "Lemme outta here!"?'
Now english is not my native language, so some subtle humour might have 
escaped me and I may have understood that entirely wrong... :-)

Good.
The fact that you were starting python from the Python31 folder, and 
then typed 'now what?' gave me the idea you did not...

Well, than you've come along quite far already, and are on the right 
list :-)
Then, please post the output of your 'python setup.py build' command, 
which will give us some clues about *why* you fail... (or, if the output 
is long, try to find the relevant lines indicating where and what goes 
wrong)

Most of us are ;-) But sometimes you just need to bite the bullet...
