py38-pytorch fails to build in buildbot

Sun Dec 1 12:23:16 UTC 2019

I’m working on porting AllenNLP models in https://github.com/macports/macports-ports/pull/5862 .

The build bot fails building py38-pytorch, which I haven’t modified within this PR. I have verified that the Python version 3.7 build of the parent py-allennlp works both locally and within the build bot.

Have I specified something incorrect in the parent Portfile for py-allennlp? Is this is known issue? Should I scale back to just Python version 3.7 for this port?
