Trying to install Denemo on MacOS 12.6 using MacPorts, fails on aubio, can't find python

[Kenneth Wolcott]

Hi;

  I like Lilypond.

  Thought I'd try Denemo.

  Successful at installing via MacPorts many of the prerequisites, but
fails on aubio.

  Apparently there are more than one version of python installed
during this process, but none of them are known as vanilla python.

Thanks in advance for the assistance.
