Question

我正在尝试使用mavericks在Macbook Pro上安装igraph 0.7.1。我使用macports安装了R 3.1.0，并在使用install.packages（＆＃34; igraph＆＃34;）安装igraph时不断收到以下警告/错误：

然后安装完成，出现以下错误：

Error : .onLoad failed in loadNamespace() for 'igraph', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/opt/local/Library/Frameworks/R.framework/Versions/3.1/Resources/library/igraph/libs/igraph.so':

我的计算机上安装了Apple LLVM 5.1版（clang-503.0.40）（基于LLVM 3.4svn）。我会非常感谢你的帮助。

提前致谢。
