  Thanks.

  After much effort to rebuilt a patched boost library, it now compiles
fine.  However, the methods that are affected by the transformation
(Schedule*) are receiving some kind of name mangling:

>>> dir(ns3.Simulator)
['Now', 'Run', 'ScheduleDestroy_126390ccfc1f22f22289536ea47d3ecb',
'ScheduleNow_3692da707df52052648f9d5435d958c4',
'Schedule_fbf096d706be19b392c1e3fbcd3bf544', 'Stop', '__class__',
'__delattr__', '__dict__', '__doc__', '__getattribute__', '__hash__',
'__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__', '__str__', '__weakref__']

  Bug?
