actually, there's a whole bunch of py2 only syntax.  looking at setup.py, it 
looks like the 2to3 hack isn't working as desired

perhaps this small addition, that fixes everything for me

setup(...
  use_2to3=True
)

It's likely you first installed psutil for python 2.x. Am I right?
In this case you have to remove build directory before installing psutil.
In summary:

$ python2.7 setup.py install
$ rm -rf build
$ python3.2 setup.py install

Please let me know if this fixes the problem.

nope, no 2.7, just 3.2.  tar xf, cd psutil.., python setup.py install, cd /,
python -c 'import psutil'

my suggested fix comes straight from the python wiki for porting 2 to 3

AFAIK use_2to3 option is for distribute only:
http://docs.python.org/dev/howto/pyporting.html#during-installation
I can add it but it shouldn't make any difference.

Have you tried to download psutil tarball again and unpack it in a brand new 
directory and then install it with "python3.2 setup.py install"?
In psutil's setup.py file we've been using the trick mentioned in the link 
above:

try:
    from distutils.command.build_py import build_py_2to3 as build_py
except ImportError:
    from distutils.command.build_py import build_py

...and that worked fine so far.
