These instructions are both unclear, and do not work. You'll have to make sure to go into greater detail on how to install the entire Qt framework, i.e. Qt and Qt Creator on OS X Snow Leopard. Not least because the documentation on the Qt site itself is confusing, it leads you around in circles when you're hunting requirements.

Here is the error I get when trying to install Qt:

cd src/tools/bootstrap/ && make -f Makefile
/Users/jeremiah/Qt/qt/src/tools/bootstrap
make[1]: Nothing to be done for `first'.
cd src/tools/moc/ && make -f Makefile
/Users/jeremiah/Qt/qt/src/tools/moc
qmake -spec ../../../mkspecs/macx-g++ -o Makefile moc.pro
make[1]: qmake: No such file or directory
make[1]: *** [Makefile] Error 1
make: *** [sub-moc-make_default-ordered] Error 2
