The INSTALL.txt file incorrectly states that Qt 4.7.x is required. Qt 4.8.x is required. I suggest that the paragraph
Qt 4.7.x is also required on all platforms. It can be downloaded
[
http://qt.nokia.com/downloads here] (choose the LGPL version).
should be replaced by
Opensource Qt 4.8.x is also required on all platforms. It can be downloaded
[
http://qt-project.org/downloads here]
