This is a problem with which I also have struggled and was never able to 
get the (..) syntax of relative imports to work so I solved it another 
way placing the following code at the top of the file containing the 
tests:

path2add = os.path.expandvars("${CLUB}/Utils")
sys.path.append(path2add)

If the first line confuses you just ignore it and assign the full path 
name to and including your 'utils.py' file to the path2add variable.
