I'm having problems installing QT on my MacBook with Lion 10.7.3 and XCode 4.3.1 installed. I tried to install with brew, and got a compiler error. Below is the end of the error, and the "brew doctor" output. It seems to be using the wrong version of gcc... although I just installed the latest XCode. Any ideas? I'm trying to install QT, so I can run headless browser tests with capybara-webkit. (I also tried with --install-from-source and got the same error.)

gstroup$ brew install qt

....

Also try: brew doctor to check your setup for common problems. brew missing to check installed packages for missing deps.

gstroup$ brew doctor

/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.

/usr/bin/gcc

gstroup$ gcc --version

Xcode 4.3.x switched away from gcc as the compiler. Now Apple uses llvm. This maybe the root of your issue. There is a Github project https://github.com/kennethreitz/osx-gcc-installer/downloads that will let you download a gcc compiler.

You may have to prefix your brew command with env CC=/usr/bin/gcc to specify the gcc compiler.
