Running ./mongod or ./mongo results in an SyntaxError:

python ./mongod
File "./mongod", line 1
SyntaxError: Non-ASCII character '\xcf' in file ./mongod on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
python ./mongo
File "./mongo", line 1
SyntaxError: Non-ASCII character '\xcf' in file ./mongo on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

I installed the package anew but the error(s) still resulted.
