Glad to hear that.

There is no "make clean". There was some discussion about that on the 
list not too long ago. It's probably fine to do "touch src/qt.mk" and 
then "make qt" again which will install over the existing one.

I think the explanation might be that QMAKESPEC is not set on their 
systems. It's not set on my opensuse 11.2 system.

Qmake finds a default qmake.conf without QMAKESPEC. Mingw-cross-env 
relies on this behavior. I don't remember the details, but I think it's 
determined by the location of qmake.

Let us know how your building goes.
