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:

START

END

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.
