Here is the list of steps that are different so far as I got, when installing MacOS with MacPorts
Steps
1) first install the C++ libraries that we would need later:
sudo port install automake libtool pkgconfig libffi gmp openssl
Note that the MacPorts has pkgconfig library name rather than pkg-config in
Brew or linuxes.
2) Next step is to build one of pyethapp dependencies - the scrypt module
using a trick. The reason for this trick is described at:
https://cryptography.io/en/latest/installation/#building-cryptography-on-os-x,
and a solution is described at: https://github.com/ethereum/pyethapp/issues/209
Basically, the pyethapp setup relies on system packages for openssl, so,
instead of modifying its setup scripts, we're going to simply preinstall the
dependency manually:
env LDFLAGS="-L/opt/local/lib" CFLAGS="-I/opt/local/include" pip install scrypt
3) Installing from an egg/wheel doesn't work, so clone the pytheapp module and run the "Development" setup
cd pyethappUSE_PYETHEREUM_DEVELOP=1 python setup.py develop
4) THE TRICKIEST: Fix the devp2p module.
In the devp2p/crypto.py fix the openssl import path. Make sure to include the
MacPorts' library into the lib path. Correct lib path below:

python3pytheapphacked in python 2.7, so it won't install from pypi on 3.6Expected behaviour
Instead of step 3, the install should go fine
Observed behaviour
required ciphers {'aes-128-ctr'} not available in openssl library'
Steps to reproduce
After the above installation start:
python[3] -m pyethapp.app
