Please include the full command used to build and install pyzmq, and the pyzmq build output, e.g.

pip install -vv --no-binary pyzmq pyzmq

I'd also recommend using libzmq4 instead of libzmq3, which is ~10 years outdated at this point, I think.

I hope I got your questions :
[philippe@jupiter ~]$ pip install -vv --no-binary pyzmq pyzmq

I will wee if I can try libzmq4

Make sure to include the output of the build itself. What you've given only shows the output when pyzmq is already installed.

Try making a virtualenv and installing with pip install -v --no-cache pyzmq to avid re-using a past build.
