Hầu hết các câu hỏi liên quan đến vấn đề này là do thiếu Xcode; Tôi đã cài đặt Xcode 4.2.
Cài đặt thử:
rvm install 1.9.3

llvm-gcc-4.2Dựa trên config.log (được đăng ở dưới cùng do kích thước) Tôi đã thử symlinking gcc-4.2 đến gcc và sau đó cài đặt:
rvm install 1.9.3
ERROR: The autodetected CC(/usr/bin/gcc-4.2) is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`, and set CC=/path/to/gcc .Vì vậy, tôi có thể chỉ cần lấy gcc ở nơi khác, nhưng tôi chủ yếu quan tâm đến lý do tại sao điều này xảy ra. Không nên cài đặt Xcode là đủ?

config.logtập tin?
Hừm; Tôi có cùng một gcc, và nó đã cài đặt tốt :( Điều thứ hai trên SO hoạt động tốt với tôi nhưng không phải cho người khác, thường thì ngược lại.

mu: Tôi đã thêm toàn bộ config.log ngay bây giờ. Không có gì bất thường đối với mắt tôi. Đây là phiên bản không có symlink. Dave: Vâng, đó là máy tính :-).

Nhờ có sự giúp đỡ từ @mpapis, tôi đã ghi lại Cách cài đặt RVM trên Mac OS X 10.8 (Mountain Lion) với Xcode 4.5 mà không cần cài đặt Công cụ dòng lệnh .
