Ah, a Mac. Note that by default, Mac builds in debug-and-release mode. So it 
compiles everything twice and the release builds take longer because of the 
optimisation passes.

Also, if you enable universal builds, you end up building a couple more times.

If you restrict yourself to debug and native builds, it should cut down 
considerably the time it takes you to build Qt.

Maybe for Mac. For Linux systems and other Unix that use gcc, it's quite easy. 
Everyone shares their idle CPU cycles.

In our network here in Oslo, my C2D of 2.33 GHz can finish a Qt 4.7 src build 
in 8 minutes.
