我一直在这里检查其他问题，来自人们在使用 RVM 在 Lion 中安装 ruby 1.9.3 时遇到问题，问题似乎与我的相同，所以我尝试了没有成功提供的解决方案：
我第一次尝试：
rvm install 1.9.3 --with-gcc=clang
返回：
Installing requirements for osx/10.7/x86_64, might require sudo password.
Skipping `brew update` make sure your formulas are up to date.
Missing required packages: libtool, pkg-config, libyaml, readline, libxml2, libxslt, openssl, sqlite.

Skipping update of certificates in '/cert.pem'.
Warning: found user selected compiler 'clang', this will suppress RVM auto detection mechanisms.

ruby-1.9.3-p392 is not installed.
To install do: 'rvm install ruby-1.9.3-p392'
注意ruby-1.9.3-p392 is not installed.接近尾声的样子。
之后我尝试按照以下建议进行操作：
CC=/usr/bin/gcc-4.2 rvm install 1.9.3 --enable-shared
但它返回了：
You requested building with '/usr/bin/gcc-4.2' but it is not in your path.
所以我基本上被困在这里，不知道如何进行。任何帮助将不胜感激。提前致谢。
