pypy failing to load jupyter notebook... why?

I am trying to load jupyter notebook with PyPy. I have done it already on different machines and I never got any problem. This time, however, (on an iMac with OSX 10.11.16) I am getting the following error message: This is the script I use to load the notebook with PyPy:

import re
import sys

from IPython import start_ipython

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(start_ipython())

I run it from bash: pypy script.py notebook If I run it without notebook, the IPython session starts as it is supposed to, so the issue must be related to the notebook but I can figure it out. Of course, zeromq is installed, but I have no idea what headers in the error message refers to... Any clue on how to solve this?

P.S. I have used pypy -m pip install jupyter to install it.

"zeromq headers" means what is necessary for developing with, as opposed to only using, the zeromq library. It may be in some "zeromq-dev" package or similar, depending on what distribution system you use on your OS/X.

Normally you'd get such an error when trying to do pip install, but in this case, "zmq" is written using the old CFFI style, deprecated since 2015; as a result it requires the headers at run-time.
