Cannot install capybara-webkit gem

Question

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
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/qt-4.8.2.mountainlion.bottle.1.tar.gz
######################################################################## 100.0%
==> Pouring qt-4.8.2.mountainlion.bottle.1.tar.gz
==> Caveats
We agreed to the Qt opensource license for you.
If this is unacceptable you should uninstall.
==> Summary

Then:

> gem install capybara-webkit

I'm really, really stuck. Is there a solution for this? Thank you so much in advance.

You might want to try removing every bit of the older Qt install. I just installed qt 4.8.4 (no previous install) from brew + capybara-webkit and had no errors. — Paul Kehrer, Feb 01 '13 at 02:00
Paul, thank you. To the best of my knowledge, the previous Qt was installed using macports. I removed all ports and macports itself. But in case there's an older version, what to look for and how to remove it? Thank you for any hints you can offer. — Marcin Bilski, Feb 01 '13 at 02:05
Based on your first error msg it looks like you may have an old QtCore here: /Library/Frameworks/QtCore.framework — Paul Kehrer, Feb 01 '13 at 02:08
I renamed the dir and now: http://pastie.org/6002106 UPDATE: Forgot to mention that I did that after renaming the dir: > brew uninstall qt > brew install qt — Marcin Bilski, Feb 01 '13 at 02:14

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
