Hello and welcome to RTEMS.

I do. :)

My mail reader says the file has a size of 0.

The build I did here ...
... has in it's build log:
checking whether to use python... /usr/bin/python
checking for python2.7... yes
This is the MacOS provided python. The RSB gdb python check support must be
finding python2 in the path posted. I do not think this is the standard one.

It is true you need the python development libraries as gdb links to the python
runtime to provide python support inside gdb. On some hosts you do just need to
install the devel support for python while others such as MacOS it is more
complicated if you are using packaging system.

I am using OS X 10.14.1 or Darwin-18.0.0-x86_64-i386-64bit. Xcode is 10,1 (10B61)).

This looks like a packaging system version to me.
My MacOS test machine does have any 3rd party packaged software installed so I
can make sure RTEMS and the RSB builds with just MacOS and Xcode installed.
This is not a comment on macports or homebrew, they are great however I need to
baseline what RTEMS provides.

You can either remove those packages or you can update and play with them until
you have something that works for you. Unfortunately I have no capacity or
equipment to support macports or homebrew builds.
