Sorry, didn't see your remark on ufc later in the mail. 
If you go to the directory 

/tmp/tmpaR40ea2010-7-20-23-30_instant/

And have a look in the *.i file there, you will see
that the ufc.i file is included as: 

%}
%import "swig/ufc.i"
%pythoncode %{
'''
%}

which means that swig needs to know where ufc.i is. 
Further, you should look in the 
setup.py file. 

The swig_cmd shows you the include files passed to swig (with -I). 

Somehow dolfin does not know about the ufc.i file, it seems.
