Is that the Trolltech recommended way for windows and the Mac?
If Trolltech required that pkg-config be installed before QT could
be used on any platform, I would have no problem using it.  
But, that does not seem to be the case, unless I am missing
something?   So, what do the Trolls say should be done if
pkg-config is not found?  I am sure many Trolltech customers
on windows do not have pkg-config and are happily using Qt,
I am assuming the answer is use qmake, which is what we are doing.

I suppose we could do some sort of hybrid approach.  
Something like this:

1. find qmake in the PATH
2. use pkg-config to find qmake
3. if 1 and 2 are the same qmake, then use the info from pkg-config
4. if pkg-config was not found, or it points to a different qmake than
the one in the users PATH, then use qmake to setup the paths for the build.
