【问题描述】：
我已经通过 Mac Ports 安装了图形工具。前几天，我跑了
$ sudo port selfupdate
$ sudo port upgrade outdated
Graph-tool 被重新编译（大约需要 30 小时（！））现在，当我想在 python 中包含 graph-tool 时，我收到以下错误：
Python 2.7.6 (default, Nov 22 2013, 13:39:24)
[GCC 4.2.1 Compatible Apple Clang 4.1 ((tags/Apple/clang-421.11.66))] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import graph_tool

我用“port installed | grep boost”测试了boost包的版本和变种：结果：
boost @1.49.0_0+python27
boost @1.53.0_1+no_single+no_static+python27
boost @1.53.0_2+no_single+no_static+python27
boost @1.54.0_0+no_single+no_static+python27
boost @1.55.0_1+no_single+no_static+python27
boost @1.55.0_2+no_single+no_static+python27 (active)
对于graph-tool本身，“port installed | grep graph-tool”的结果是：
py27-graph-tool @2.2.25_0
py27-graph-tool @2.2.29_0
py27-graph-tool @2.2.29.1_0 (active)
这是当我检查错误消息中出现的库链接到哪些库时的结果：
$ otool -L /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/libgraph_tool_core.so
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/libgraph_tool_core.so:

/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)
有人有想法吗？
谢谢，

在这个post，建议做
$ otool -L /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python。 -
结果是：
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 744.19.0) -
您的设置中默认的编译器是什么？您是否可能升级了操作系统，并且没有重新安装 Xcode 和开发人员工具？这是使用 MacPorts 时的一个主要警告，我在
otool输出中看到共享对象与系统的 C++ 标准库链接。 -
Macports 使用的编译器应该是 clang。我从未更改过 Macports 的设置。我现在正在更新 Xcode，并将重新编译 python 和 boost。
-
重新编译 python、boost 和 graph-tool 没有帮助。我仍然得到同样的错误。通过调用
nm -a /opt/local/lib/libboost_python-mt.dylib，我发现符号__ZN5boost6python7objects23register_dynamic_id_auxENS0_9type_infoEPFNSt3__14pairIPvS2_EES5_E确实不包含在那里。然而，有一个非常相似的符号：__ZN5boost6python7objects23register_dynamic_id_auxENS0_9type_infoEPFSt4pairIPvS2_ES4_E，如果这意味着什么。
