This looks like an error caused by your Python version, in connection with
some code in lib/ma28/libinfo.py that works properly only with Python2.

The simplest workaround would be to ensure that the ./setup command uses 
python2, if that is available on the system. Fixing the syntax in 
libinfo.py so that it works with Python 2 and 3 also should not be hard.
