So decided to get ambitious and get git source and try to build...
I Don't see an option to build without 'acceptance-tests'

so instead I get

make[2]: Entering directory '/home/d3x0r/addons/srcpit/mono/acceptance-tests'
  File "versions.py", line 11
    print "Not found"
                    ^
SyntaxError: Missing parentheses in call to 'print'
  File "versions.py", line 11
    print "Not found"
                    ^
SyntaxError: Missing parentheses in call to 'print'
  File "versions.py", line 11
    print "Not found"
                    ^
SyntaxError: Missing parentheses in call to 'print'
  File "versions.py", line 11
    print "Not found"
(repeated several more times)

added parens to all print statements and no more issues; though that
was also the last thing; maybe it wasn't an error stopping the
build....
