Python Question

Python3, lxml and "Symbol not found: _lzma_auto_decoder" on Mac OS X 10.9

I have installed python 3 using homebrew and afterwards installed pip3 and lxml.

The following line

from lxml import entree

leads to the following error:

$ python3

>>> from lxml import etree
Traceback (most recent call last):

Does anybody know how to fix this?
