I installed v 0.97 yesterday with related updates based on macports etc. based 
on your 
'how to install on mac os x lion'
I am running Xcode 4.2.1, os 10.7.2

I ran scons without changes.

1--->
with swig but without the swig-python port installed I noticed a swig error.
2--->
with the swig port and related swig-python installed the following resulted:
