Seems to be incompatible with python 2.7

[cjeanneret]

It seems to be incompatible with debian squeeze python2.7 - something has changed in ctypes maybe?
Error ca be seen whily running python list-config.py :

main.actions.manualfocusdrive =
Traceback (most recent call last):
  File "list-config.py", line 5, in <module>
    C.list_config()
  File "/home/user/devels/dslrPi/piggyphoto/piggyphoto/__init__.py", line 360, in list_config
    self._list_config(cfg, cfglist, cfg.name)
  File "/home/user/devels/dslrPi/piggyphoto/piggyphoto/__init__.py", line 352, in _list_config
    self._list_config(c, cfglist, path + "." + c.name)

    value = ctypes.cast(value.value, ctypes.c_float_p)
AttributeError: 'module' object has no attribute 'c_float_p'

I'm using this lib against a Nikon d90:

gphoto2 --get-config /main/actions/manualfocusdrive
Label: Drive Nikon DSLR Manual focus                                           
Type: RANGE
Current: 0
Bottom: -32767
Top: 32767
Step: 1

Python version: 2.7.3rc2

According to python documentation, there is no such attribute "c_float_p":
http://docs.python.org/2/library/ctypes.html#fundamental-data-types

Thanks for your help !

Cheers,
