qmake doesn't make a 'make' file

I'm trying to build an application for OS X following the Qt instructions. I'm using the example program plugandpaint. But the basic 3 lines necessary don't work:
make clean
qmake -config release
make

The result of make is:
make: *** No targets specified and no makefile found. Stop.
This is what happens if there is no make file in the plugandpaint directory.

qmake executes but appears to create an xcode project instead of a make file.

What am I missing here?

You also have to pass "-spec macx-g++" that qmake creates a Makefile. You can also link that spec file to default then you must not type it every time. (should be somewhere in /usr/local/QtXXX/mkspecs/)
