That seems like a lot of effort, unless you really don't want to emerge a testing version of a package. There is now an ebuild (testing) in the tree for 3.5, and it also requires a testing version of dev-python/psutil. It looks like some version incompatability snuck in with some upgrade of either pgAdmin4 or python. I wonder if selecting a different version of python would work? 3.5 uses localhost:40429, although I suppose that is configurable. In addition, I really had to hunt to figure out how to stop the program. Just closing the web browser does not stop the pgAdmin4 server process - to close that you have to find it in the system tray, and shut it down from there.
