I was hoping you wouldn't say that :-\

Well I do have the entire build process captured to a file. So that may help.
I am guessing that there was something amiss with either ada ( gnat ) or go.
Simply because the results I did get, were fairly horrific for gnat and go :

where I see :

eek :-P

For the sake of experimentation I will drop both ada and go from the list of 
languages to build for, just to see what I get.  However I guess I have to
grep through the output from the build to see w5 : what, where, why it went wrong.
