Duplicate properties when querying\setting Qmake environment variables

[gogfather]

I'm running into the "Could not find mkspecs for your QMAKESPEC..." error when trying to build Qt 4.7.3. Reading the documentation you can use "qmake -set VARNAME VARVALUE" to set these properties. I set them all to the appropriate directories and they seemed to have worked. When I run a "qmake -query", it lists all of my changes as well as the values it had before! When I run qmake in the Qt build, it of course references the old values, not the new ones I set. I only have one version of Qmake in my path and I verified that the QMake versions I set and use in the build are the same. (v2.01a). Here's the "qmake -query" output.

The first set of value are the ones I set, the second set were somehow set by default. Can anybody let me know how to set it properly?
