Binary package hint: python2.7

On Maverick with python2.7 (2.7-6 deb version), the multiprocessing
module fails to operate:

python2.7 -c 'import multiprocessing; multiprocessing.Pool()'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/multiprocessing/__init__.py", line 227, in Pool
    return Pool(processes, initializer, initargs, maxtasksperchild)
  File "/usr/lib/python2.7/multiprocessing/pool.py", line 89, in __init__
    self._setup_queues()
  File "/usr/lib/python2.7/multiprocessing/pool.py", line 181, in _setup_queues
    from .queues import SimpleQueue
  File "/usr/lib/python2.7/multiprocessing/queues.py", line 22, in <module>
    from multiprocessing.synchronize import Lock, BoundedSemaphore, Semaphore, Condition
  File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 33, in <module>
    " function, see issue 3770.")
ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.
