[QtonPi] QtonPi Digest, Vol 10, Issue 12

Thanks a lot for your script Kerian. I have tried it and had no major
issues, but I wanted to do it step by step by myself too :)
Regarding http://qt-project.org/wiki/RaspberryPi_Beginners_guide I had some
troubles:
- build of qtbase will fail unless I add -no-pch option to configure. While
its documented (on a different page), I wonder if it's a common issue. I
used a fresh install Ubuntu 12.04 (in a virtual box)
- in the setup of QTCreator the wiki says to use /usr/local/qt5pi/bin/qmake

 I repeatedly had an error stating that qt was not properly installed and I
would need to run make install again, until I replaced the aforementioned
path with /opt/qt5/bin/qmake then it worked (while I am being warned that I
have no qmlviewer)

I'm still too much of a newbie on both RPI and QT to propose these changes
to the wiki page but I would be curious to hear from you guys about these
two observations.. Then I'll suggest the wiki change

Regards
JC
