libiio fails to build under MacOS 10.14.6

[mcquiggi (Kevin McQuiggin)]

Hi There:

I'm a longtime user of MacPorts, thanks to all you folks for creating this service and keeping the thousands of ports running!

I am a gnuradio user and am trying to install libiio and gr-iio on my system, which runs MacOS 10.14.6.

When I "port install libiio" I get the following messages and the port fails to install. It seems to build, but then fails due a problem with /opt/local/lib/python3.7:

I have /opt/local/lib/python3.8, but indeed there is no /opt/local/lib/python3.7.

This seems to be a problem with the install script looking for Python 3.7 but not seeing it as I have Python 3.8.

Any help appreciated. Just wanted to let you know that the install portion of the port is broken.

Please attached the build log as noted toward the END portion of the noted text. I'm guessing this is a duplicate of #60669 ... just a guess without the build log!

Hi Michael:

The build/install log has now been attached to this ticket!

Thanks in advance,

Kevin
