This is really a tough one for me. I'm trying to migrate over to Mountain Lion but I get the following when trying to install capybara-webkit.
The initial error:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

So I installed the latest qt using homebrew:
> brew install qt

If this is unacceptable you should uninstall.

I'm really, really stuck. Is there a solution for this? Thank you so much in advance.
回答1:
Whoa! I followed Paul's advice (THANK YOU Paul!) plus linked qmake to the new version. (Was 4.7.3, I needed it to use the latest 4.8.2).
Hint: qmake -v to see which version is in use.
Had I only known this... :P
