 I’m trying to install gerbv.

 One of the huge number of dependencies is gtk. Doing a sudo port install
 gtk3 results in the following error:

 Error: Failed to fetch python26: python26 cannot be built for Apple
 Silicon

 I already have python39 installed. Is there any way to get gtk to use
 that?
