终端输入 git svn ... 时，如下报错：

解决方案：
sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/SVN/ /Library/Perl/5.18/SVN
sudo mkdir /Library/Perl/5.18/auto
sudo ln -s /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level/auto/SVN/ /Library/Perl/5.18/auto/SVN
