I got mine to work by following wiraone's advice, so i'll try and explain step-by-step how to do it..
Then as root rpm -Uvh redhat-config-packages-1.2.7-1.src.rpm
cd to /usr/src/redhat/SOURCES
tar zfx redhat-config-packages-1.2.7.tar.gz
cd to redhat-config-packages-1.2.7/src
edit the line that wiraone said to edit
save your changes and go back to /usr/src/redhat/SOURCES
rm the redhat-config-packages-1.2.7.tar.gz
now we'll remake it, but with the changes
tar cf redhat-config-packages-1.2.7.tar redhat-config-packages-1.2.7/
rpmbuild -bb redhat-config-packages.spec
thats it, now we just have to install it:
rpm -Uvh redhat-config-packages.rpm
and thats should be it!
Any problems or anything, just ask
