After numerous failed attempts I decided to try on my laptop
OSX 10.13.6 High Sierra
Xcode 10.1
Took many hours but built and installed successfully.
I then copied the built system to my Catalina computer and ran make install which went fine until:

However, installation appears to have been successful to some extent:
 obj % /usr/local/bin/gnat --version

I've yet to see if it actually  works.
