Is ucpp.so installed

Using fresh svn checkout, I've did:

   ./autogen.sh
   python setup.py build
   python setup.py install --prefix=`pwd`/iii

After that, the "iii' directory does not have the "ucpp.so" extension module, 
and Synopsis does not work. I can workaround this by adding the path to 
source directory of ucpp.so, but I think it's not right?

Am I missing something?
