我已经下载了CVtypes并尝试了示例脚本，但无法使其正常运行。我得到的错误是：
pete@pete-MacBookPro:~/python_scratch/cvtypes$ python showcam.py
Traceback (most recent call last):
File "showcam.py", line 1, in <module>
from CVtypes import cv
File "/home/pete/python_scratch/cvtypes/CVtypes.py", line 580, in <module>
_cxDLL = cdll.cxcore100
File "/usr/lib/python2.6/ctypes/__init__.py", line 423, in __getattr__
dll = self._dlltype(name)
File "/usr/lib/python2.6/ctypes/__init__.py", line 353, in __init__
self._handle = _dlopen(self._name, mode)
OSError: cxcore100: cannot open shared object file: No such file or directory
我已经安装了所有这些软件包，我认为它们包含了所需的库：
libcv-dev - development files for libcv
libcv2.1 - computer vision library
libcvaux-dev - development files for libcvaux
libcvaux2.1 - computer vision extension library
libhighgui-dev - development files for libhighgui
libhighgui2.1 - computer vision GUI library
opencv-doc - OpenCV documentation and examples
python-opencv - Python bindings for the computer vision library
