我正在尝试使用 MacPorts 安装 Python 版 graph-tool，但由于某种原因，它无法安装。我检查了端口日志，发现了很多错误，如下所示：
:info:build ./../fast_vector_property_map.hh:136:7: note: candidate constructor (the implicit copy c\
onstructor) not viable: requires 1 argument, but 2 were provided
:info:build class unchecked_vector_property_map
:info:build ^
:info:build fatal error: too many errors emitted, stopping now [-ferror-limit=]
:info:build 20 errors generated.
和这个：
:info:build In file included from graph_eigenvector.cc:24:
:info:build ./graph_eigenvector.hh:44:23: error: no matching constructor for initialization of 'boos\
t::unchecked_vector_property_map<double, boost::vec_adj_list_vertex_id_map<boost::no_property, unsig\
ned long>>'
:info:build CentralityMap c_temp(vertex_index, num_vertices(g));
:info:build ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
最后
:info:build Exit code: 2
:error:build org.macports.build for port py27-graph-tool returned: command execution failed
:debug:build Error code: CHILDSTATUS 22204 2

我不太明白发生了什么。我还尝试手动安装 graph-tool，但无法使所有依赖项（特别是 pycairo）正常工作。可能发生了什么？MacPorts 是否可能错误地安装了某些依赖项
