Here is the code snippet I used when I was supporting older Python versions:

try:
    import json # python 2.6
except ImportError:
    import simplejson as json # python 2.4 to 2.5
try:
    _tmp = json.loads
except AttributeError:
    import warnings
    import sys
    warnings.warn("Use simplejson, not the old json module.")
    sys.modules.pop('json') # get rid of the bad json module
    import simplejson as json
