Upgraded to importlib.

    import sys

    import time

    import importlib

    # check ..

    if "." not in moduleclass:

    # import this module with the specified class:

    try:

        # ~ this sometimes fails if module file was just copied to a newly created directory ...

        # mod = __import__( modulename, fromlist=[classname] )

        # ~ this seems to work for the moment ...

        fp, pathname, description = imp.find_module(modulename, sys.path)

        mod = imp.load_module(modulename, fp, pathname, description)

        mod = importlib.import_module( modulename )

    except ImportError:

        logging.error('Could not import module "%s" ...' % (modulename))

        logging.error("Search path:")
