Error when attempting to compile and download software to the Propeller Activity Board

Hi All,

SBC: NVIDIA Nano 4GB
OS: Jetpack 4.6/Ubuntu 20.04 (upgraded from Ubuntu 18.04)
ROS: Noetic

When I run this sequence of commands to load the Arlobot Propeller software:

cd ~/catkin_ws/src/ArloBot/PropellerCodeForArloBot/ROSInterfaceForArloBot/
mkdir bin
cd bin
rm -rf *
cmake -G "Unix Makefiles" ..
make run # Remember, make run installs it to EEPROM

And I run cmake -G "Unix Makefiles" .. I get the following:

thomas@thomas-desktop:~/catkin_ws/src/ArloBot/PropellerCodeForArloBot/ROSInterfaceForArloBot/bin$ cmake -G "Unix Makefiles" ..
-- Found PropWare: /usr/share/PropWare/CMakeModules/PropellerToolchain.cmake (found version "3.0.0.224")
-- The C compiler identification is unknown

CMake Error at /usr/share/cmake-3.16/Modules/CMakeTestCCompiler.cmake:60 (message):
The C compiler

"/opt/parallax/bin/propeller-elf-gcc"

is not able to compile a simple test program.

It fails with the following output:

I get the following error message:

CMakeError.log output:

Compiling the C compiler identification source file "CMakeCCompilerId.c" failed.

The output was:

I appear to have two versions of "propeller-elf-gcc" in /opt/parallax/bin:
propeller-elf-gcc
propeller-elf-gcc-4.6.1
Is it possible to use only "propeller-elf-gcc-4.6.1" which is one I think I should be using?

Any ideas as it looks like there is an punctuation issue with "CMakeCCompilerId.c"?
I have attached a copy of the CMakeCCompilerid.c which looks somewhat different than other CMakeCCompilerid.c that I have viewed on the IoT.
