我安装了Homebrew，并根据说明运行brew doctor来查找问题。
然后我跑了brew prune并移动了Macports。
显然卸载Macport会导致更多问题。它在一个新目录中。我该怎么办呢？
这就是发生的事情：
~ $ brew doctor

Warning: Broken symlinks were found. Remove them with `brew prune`:
/usr/local/bin/bbdiff

Warning: You have MacPorts or Fink installed:

This can cause trouble. You don't have to uninstall them, but you may want to
temporarily move them out of the way, e.g.
sudo mv /opt/local ~/macports

谁能告诉我接下来的步骤？什么是＆＃34;意外的头文件？＆＃34;
