 Replying to [comment:4 ryandesign]:
 > py-onnx is a new port that
 [https://build.macports.org/builders/ports-10.15_x86_64-builder/builds/20471/steps
 /install-port/logs/stdio exhibits this problem]. Steve, any comment about
 why you needed to use both portgroups?

 I included the {{{cmake}}} portgroup because the build needs {{{cmake}}}
 stuff, and I just copied and pasted what other ports had done.

 For the areas where {{{cmake}}} conflicts with the {{{python}}} portgroup,
 I just wrote over the necessary commands.

 Also, this is only an issue in the stub port {{{py-onyx}}}, not in actual
 ports like {{{py37-onnx}}}, so it’s not an actual issue.

 I’m happy to change this to either incorporate a different {{{cmake}}}
 approach, or to add the necessary stuff to the stub port to make the stub
 port errors go away. I’ll defer to you all for the right approach.
