我正在尝试在 Mountain Lion 中使用 RVM 安装 Ruby，并在运行 make 时不断出错，即使我使用 gcc=clang 这样做（正如其他帖子上推荐的解决方案）。我已经安装了命令行实用程序更新了 XCode。

make.log 读取

当我没有指定 gcc 时也是如此，当我尝试按照此处的建议使用 openssl 和独立 gcc 包进行安装时

rvm install 1.9.3 --with-openssl-dir=$rvm_path/usr

虽然当我尝试指定我的本地 gcc 时，我被告知它不在我的路径中：

$ CC=/opt/local/bin/gcc-apple-4.2 rvm install ruby-1.9.3-p194 --enable-shared --without-tk --without-tcl
You requested building with '/opt/local/bin/gcc-apple-4.2' but it is not in your path.

任何帮助将非常感激。非常感谢。
