Ticket 48949 - os.makedirs() exist_ok not python2 compatible, added try/except
    
    Bug Description:  os.makedirs on python3 takes an option that allows ignoring
    the error if the directory does not exist in python2. This should be made more
    portable by the use of the exception handling mechanism.
    
    Fix Description:  Wrap the call in a try except to handle osError.
