Actually it does - but :)
On Mac OS the environment used for applications is *not* the  
environment you get when starting the Terminal application. Instead it  
is the environment used for applications is determined at user login  
from a file
~/.MacOSX/environment.plist
in your home directory.
You find more information on this here:

under "User Session Environment Variables".
On the other hand the Qt installer should install the qmake binary  
also to /usr/bin/qmake, which should be in the default path that is  
used for applications. Do you have the file /usr/bin/qmake?

Please set the path for you additional Qt version in Preferences->Qt4  
to /usr/local/Qt4.4 .
Actually I don't find any binaries in /usr/local/Qt4.4, so creator  
should actually not tell you that it found Qt in this case.

Thank you!
