PowerNow cool and quiet

[blackman at pharm.uoa.gr]

It seems that powernow cool and quiet is not compiled since when I modprobe
powernow_k8 says fatal module not found... So I got no cool and quiet...

I tried to configure nad then compile the kernel
make xconfig did not work and returned :

/usr/bin/ld: cannot find -lqt
collect2: ld returned 1 exit status
make[1]: *** [scripts/kconfig/qconf] Error 1
make: *** [xconfig] Error 2


make menuconfig worked but then after saving the configuration I did make and
give this error-- 

scripts/kconfig/confdata.c:88: warning: pointer targets in passing argument 1 of
‘conf_expand_value’ differ in signedness
