我在裝有Lion 10.7.3和XCode 4.3.1的MacBook上安裝QT時出現問題。我試圖用brew安裝，並得到一個編譯器錯誤。下面是錯誤的結尾，以及「brew doctor」輸出。它似乎使用錯誤版本的gcc ...雖然我剛剛安裝了最新的XCode。有任何想法嗎？我試圖安裝QT，所以我可以用capybara-webkit運行無頭瀏覽器測試。 （我也試過用--install-from-source得到同樣的錯誤。）如何在安裝了XCode 4.3的Lion 10.7.3上安裝QT？
gstroup$ brew install qt

/usr/bin/gcc Your gcc 4.2.x version is older than the recommended version. It may be advisable to upgrade to the latest release of Xcode.
We couldn't detect gcc 4.0.x. Some formulae require this compiler.
/usr/bin is in your PATH before Homebrew's bin. This means that system- provided programs will be used before Homebrew-provided ones. This is an issue if you install, for instance, Python.
Consider editing your .bashrc to put: /usr/local/bin ahead of /usr/bin in your $PATH.
Some brews install binaries to sbin instead of bin, but Homebrew's sbin was not found in your path.
Consider editing your .bashrc to add: /usr/local/sbin to $PATH.
