我正在尝试将被子配置为能够进行制作和安装，以便在 mac 上构建 csipsimple (http://code.google.com/p/csipsimple/wiki/HowToBuild)，但是，我遇到了以下问题当我尝试配置被子时。我安装了macports。
Sorry, you have a version of sed which doesn't understand constructs
of the form (foo|bar). quilt needs it. If you have access to
a version of sed which does understand such constructs, you can supply
its path with the '--with-sed=' option.
谢谢你的帮助。
