Building necessitas alpha4

[Peter Saunderson]

Thanks for that, it will save me time. By the way I noticed when I 
pulled the QtCreator from git the .gitignore seems to have ignore of 
lib/* and in lib/qtcomponents there seem to be a few files that are not 
created in the build process..  Perhaps the .gitignore is not correct 
forgit://anongit.kde.org/android-qt-creator.git 
<git://anongit.kde.org/android-qt-creator.git> ?
