我试图在OSX Lion上安装Imagemagick，但有些东西没有像预期的那样工作。

-> brew install imagemagick

/usr/local/git/bin/git
==> Cloning https://github.com/adamv/ImageMagick.git
Cloning into /Users/klebershimabuku/Library/Caches/Homebrew/imagemagick--git...
fatal: https://github.com/adamv/ImageMagick.git/info/refs not found: did you run git      update-server-info on the server?
Error: Failure while executing: git clone --depth 1 https://github.com/adamv/ImageMagick.git /Users/kleber/Library/Caches/Homebrew/imagemagick--git

酿酒医生说:

-> brew doctor
We couldn't detect gcc 4.0.x. Some formulae require this compiler.

Some "config" scripts were found in your path, but not in system or Homebrew folders.

`./configure` scripts often look for *-config scripts to determine if software packagesare installed, and what additional flags to use when compiling and linking.

Having additional scripts in your path can confuse software installed via Homebrew if the config script overrides a system or Homebrew provided script of the same name.

/Users/kleber/.rvm/gems/ruby-1.9.2-p180@global/bin
passenger-config

Setting DYLD_LIBARY_PATH can break dynamic linking.
You should probably unset it.

是的，我已经安装和运行XCode 4.1。

-> brew update
