Still running into build issues

Still running into build issues

Hi all, 

I am still running into build issues. I removed the Makefiles from the following directories :-

a. qrpgedit
b. qrpgengine
c. qrpgedit-build-desktop
d. qrpgengine-build-desktop

For completness sake also removed the files *.pro.us* from qrpgedit & qrpgengine but still get this message :-

Starting: "/usr/bin/qmake-qt4" /home/shirish/games/orange-engine/qrpgedit/qrpgedit.pro -r CONFIG+=debug -spec /usr/lib64/qt4/mkspecs/linux-g++
Failure to read QMAKESPEC conf file /usr/lib64/qt4/mkspecs/linux-g++/qmake.conf.
Error processing project file: /home/shirish/games/orange-engine/qrpgedit/qrpgedit.pro
The process "/usr/bin/qmake-qt4" exited with code 3.
Error while building project qrpgedit (target: Desktop)
When executing build step 'qmake' 

I tried to check if the export was not functioning as it should but it seems to be there, holding :- 
$ echo $QMAKESPEC
/usr/share/qt4/mkspecs/linux-g++ 

Now can somebody share with me from where the values of /usr/lib64/ are coming ?
