Comment (by RobK88):

 Many many thanks Ken.  I learned a lot!  Now I know how easily modify
 existing ports.  I wish that info was in the Macports Guide on the web.


 P.S.  One day I will figure out how to create a local Macports repo
 holding my own ports.

 By the way, I following your instructions and modified the existing Hamlib
 port by adding "configure.args-append --with-python-binding".  But the
 port still failed to compile.

 I suspect you compiled the modified Hamlib port on a Mac with a newer OS.
 Unfortunately, Python appears to be broken in many places on Lion and Mtn
 Lion.

 I will likely need to give up soon using Python (via Macports) or just
 retire this old Mac.

 Or I might try uninstalling Python via Macports and installing the latest
 version of Python available for Lion from https://www.python.org/downloads
 /mac-osx/
 (which is Python 3.7.6) and see if that works better.

 It still looks like swig and swig-python are broken on Lion (and likely
 broken on Mtn Lion as well).  Otherwise your modified hamlib port would
 have compiled okay.
