rpm -qa | grep gcc reports gcc-c++-4.1.2-33 ... what version should I be 
using? What version does qpatch expect or what was qpatch built with?

Speaking of qpatch, you recommended recompiling the program - i is the 
source qpatch for that in the Qt 4.7 distribution? (find ./ -name 
"*qpatch*" in the qtsdk-2010.05 reports just ./bin/qpatch, no sources or 
pro file matching that name.)

Once recompiled, what args are needed to run qpatch to effect the same 
outcome as if it was run during the installation?

Thanks for your help!
