在 OSX 上安装 pygraphviz 时出错

我正在尝试圖形模型在 Snow Leopard 上工作（来自 django-command 扩展）。它需要 pygraphviz，我通过 macports 安装了它。成功安装后，我收到此错误：

>>> import pygrahphviz
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named pygrahphviz
>>> import pygraphviz
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.6/site-packages/pygraphviz-1.1-py2.6-macosx-10.6-universal.egg/pygraphviz/__init__.py", line 54, in <module>

  File "/Library/Python/2.6/site-packages/pygraphviz-1.1-py2.6-macosx-10.6-universal.egg/pygraphviz/agraph.py", line 19, in <module>
    import graphviz as gv
  File "/Library/Python/2.6/site-packages/pygraphviz-1.1-py2.6-macosx-10.6-universal.egg/pygraphviz/graphviz.py", line 7, in <module>
    import _graphviz
ImportError: dlopen(/Library/Python/2.6/site-packages/pygraphviz-1.1-py2.6-macosx-10.6-universal.egg/pygraphviz/_graphviz.so, 2): Symbol not found: _Agdirected

有什么建议么？

您正在使用 Apple 提供的 python，而不是通过 macports 安装的 python

用于sudo port select python ,python-version>将正确的 python 链接放入 /opt/local/bin/python 中
