I've encountered similar problem to: https://bugs.archlinux.org/task/22800
When I'm trying to import 'pyopencl' in python 3.2.3 I see this error:
>>> import pyopencl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.2/site-packages/pyopencl/__init__.py", line 4, in <module>
import pyopencl._cl as _cl
ImportError: /lib/libboost_python.so.1.50.0: undefined symbol: PyClass_Type

But everything works fine for python2-pyopencl, apparently boost is not compiled with Python3 support.
This task depends upon

I confirm the problem.

Ionuț : Is there something that would prevent us from building boost with python 3.3.0 ?

Same thing happens if luxrender is installed and pylux is imported:

python -c 'import pylux'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: /usr/lib/libboost_python.so.1.50.0: undefined symbol: PyClass_Type

I've the same error.

You probably must compile lib-boost also with the python3 protocol.

python2-pyopencl works fine.

Attached patch uses --boost-python-libname to select correct libboost_python for Python 3.
