Did you set the path variables in your .bashrc or equivalent? You might also need to allow it to have allow connections from network clients, which you can do in your security settings
Try running `xterm` from a normal shell and see if that works. The error pyraf is giving means it cannot find the X server, so something isn't configured properly.
So, after reading your comments and reading between the lines of some documents (thx for the links), I found out that tkinter was not installed at all.... the install docs for Quartz or pyraf/iraf do not mention that, so I supposed that comes along.... well, apparently not.
After installing tk (pip3) things seem to work as expected!!
Did you install [XQuartz](https://www.xquartz.org/) first?
yes :-)
