Russianpip install pylibmc==1.2.3
I get numerous build errors and the install eventually fails. Made sure, insofar as I can tell, that all the necessary packages were installed. Here is what I'm seeing when it fails:

EDIT:
Is the problem with Python 3? Does pylibmc not support it?
المحلول
As you might already have found out, there's a py3k branch which enables Python 3 support, but it is not released yet. This is how I managed to install pylibmc from py3k branch on Python 3.4.0:
sudo apt-get install python3-dev
sudo apt-get install libmemcached-dev
pip install git+https://github.com/lericson/pylibmc.git@py3k
Hope this helps.
