Bug 737952 – games-util/nml-0.4.5-r2 with Python 3.8 - nmlc: An internal error has occurred: Location: File "/usr/lib/python3.8/site-packages/nml/generic.py", line 332, in print_progress

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Matthew Smith 2020-08-18 21:21:06 UTC]

games-util/nml-0.4.5-r2 tries to call `time.clock()` which was removed in Python 3.8. This prevents other packages like games-misc/opengfx-0.5.5 from installing.

Upstream bug: https://github.com/OpenTTD/nml/issues/52
Upstream fix: https://github.com/OpenTTD/nml/commit/5b8764c3c4079941fab7be8d9086c38a88ae09ba

The fix is included in version 0.5.0 so I think a bump to the latest version will fix.

If a version bump is not possible for whatever reason, the copying the fix patch into /etc/portage/patches/games-util/nml worked just fine for me. I can now get back to my virtual train network :)
