Lion 10.7.3とXCode 4.3.1がインストールされたMacBookにQTをインストールする際に問題があります。私はbrewでインストールしようとしましたが、コンパイラエラーが発生しました。以下はエラーの終わりで、 "Brew Doctor"の出力です。それはgccの間違ったバージョンを使用しているようです...私はちょうど最新のXCodeをインストールしましたが。何か案は？私はQTをインストールしようとしているので、capybara-webkitでヘッドレスブラウザテストを実行できます。 （私も--install-からのソースで試してみましたし、同じエラーを得た。）XCode 4.3をインストールしたLion 10.7.3にQTをインストールするにはどうすればよいですか？
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.
