Build script fails on Ubuntu 12.04

[thanasik]

I've been wanting to try this out for a while, and I got to it today. I used the example code in the README, ran a quick npm install node-qt and I get an error saying that the build script fails, among other things. Any ideas why this is? Thanks in advance.

Should also mention that I also retried it by installing directly from the source repo here on Github, and it still responds with the same script failure.

@karysto pkg-config says you don't have qt-core and other stuffs installed on your ubuntu. After you install qt, try pkg-config --libs-only-l QtCore QtGui QtTest and try install node-qt again :).
