我正在尝试使用git svn来克隆包含外部的存储库。在我的Windows7机器上它完美运行。在我的Mac上，它在创建空本地存储库后无声地失败。
与此相关的一些问题的帖子已有两年多了，所以我希望情况有所改变。
我尝试过使用XCode安装的Git和SVN版本，以及安装了HomeBrew和MacPorts的新版本。最新版本的Git（2.7.2）就是我用故障排除的那个。
我发现线程需要将SVN Perl模块链接到Perl运行时搜索的目录中，并且做了类似的事情：
sudo ln -s /opt/local/lib/perl5/vendor_perl/5.22/darwin-thread-multi-2level/SVN /opt/local/lib/perl5/site_perl/5.22/darwin-thread-multi-2level/SVN
sudo ln -s /opt/local/lib/perl5/vendor_perl/5.22/darwin-thread-multi-2level/auto /opt/local/lib/perl5/site_perl/5.22/auto
如果我尝试打开Git的调试器，就像这样：
GIT_TRACE=1 git svn clone -s https://my-remote-repo
我得到了一堆类似于下面的冗余消息，当Git遇到第一个外部引用时发生了一些可疑的事情：
...

16:49:19.814647 git.c:348 trace: built-in: git 'config' 'svn-remote.svn.tags-maxRev' '45172'
如果我像这样运行Perl调试器：
PERLDB_OPTS="NonStop frame=5" /opt/local/bin/perl5.22 -d $(git --exec-path)/git-svn clone -s https://my-remote-repository
我崩溃之前就得到了以下的stacktrace。看起来多个进程正在向TTY发送输出，因此堆栈跟踪是交错的。

问题：我可以在我的MacBook上使用Git / SVN吗？如果没有，我可以利用其他替代方案吗？
