building QT 4.6.2 Segmentation fault

I am trying to install QT 4.6.2 on IBM CELL QS20 x86 ppc 64-bit machine with fedora 7. RAM on the machine is 1 GB and I have defined swap size of 2 GB. After configure I run gmake, it runs for couple of hours and then it exits with “segmentation fault”

My configure is

./configure -v -platform linux-g++-32 -debug -shared -prefix /usr/local/Trolltech/qt -no-qt3support -I/usr/include -I/home/saad/mesa/include/GL -L/usr/lib -L/usr/lib/mesa/lib -L/usr/lib/mesa/lib/gallium -opengl desktop -nomake examples -nomake demos

And the error is
collect2: ld terminated with signal 11 [Segmentation fault]
gmake[1]: *** [../../../../lib/libQtWebKit.so.4.6.2] Error 1
gmake: *** [sub-webkit-make_default-ordered] Error 2

So any ideas what can be the problem?
If I use –no-webkit then it runs fine but I need webkit to install Qtcreator, if someone can advise me how to install Qtcreator without webkit I will be most happy or help me in finding the solution for this Segmentation fault.

Thanks a lot
