We have this problem in w.c.s (http://wcs.entrouvert.org), I use this
version of your work around, just after calling enable_ptl():

enable_ptl()

import sys
# Make ihooks works under python-2.6, problem is that ihooks is broken AND
# deprecated, and so will be removed in python-3.0 without being repaired
# before and there no transition module.
# The exact problem is that the ihooks __import__ implementation does not
# handle the last argument 'level', which is used to do 'relatives' import
if sys.version_info >= (2, 6):
    import __builtin__
    import ihooks
    __old_importer = __builtin__.__import__
    __very_old_importer = ihooks.current_importer.save_import_module
    def __import_wrapper(name, globals={}, locals={}, fromlist=[],
level=-1):
        if level == -1:
            return __old_importer(name, globals, locals, fromlist)
        else:
            return __very_old_importer(name, globals, locals, fromlist,
level)
    __builtin__.__import__ = __import_wrapper
