In building there are some errors:

You cannot build Photivo with GCC 4.5. At least 4.6 is required because of its 
C++11 support. If you start thinking about updating your compiler I’d suggest 
to go straight to 4.7 because we *may* update the requirement in the not too 
distant future.

Also note that the minimum required Qt version is 4.7.

Good idea. Done.
And to do things right I added a check for GCC 4.6+ to photivo.pro as well. :)
