py27 is no longer supported for most (all?) Enthought packages. See ​https://github.com/macports/macports-ports/pull/6590

[jjstickel (Jonathan Stickel)]

I attempted to update the py-enable Portfile to the latest version with python-3 subports. However, it errors on the build step, and it is not immediately obvious to me what the fix might be. I do not have sufficient interest to fix it. Enable is a dependency for Chaco, and I have no idea if there is a user-base in Macports for Chaco.

Should I submit a PR with these changes and include a Portfile note that it is broken? Or leave the port as is?

[jmroot (Joshua Root)]

Leaving as is isn't an option since that will leave both enable and chaco unable to be installed. Either delete the ports that depend on py27-traitsui, or restore py27-traitsui. Adding python 3 subports is a separate problem that can be done (or not) afterwards.

py-chaco

[jjstickel (Jonathan Stickel)]

The latest release version of enable (4.8.1) does not work with python-3.8, although enable#master should be OK. Since I am not interested in maintaining this port, I removed py-enable (and py-chaco) in PR ​https://github.com/macports/macports-ports/pull/9504. I attached revised Portfiles here in case someone wants to re-add these ports at some point.
