A pair of useful find commands to fix up file/directory permissions...
(tweak the chmod commands to suit your needs)

find . -type d -exec chmod 2770 {} \;
find . -type f -exec chmod 660 {} \;


If you do a lot of rpm building, then maybe you don't want to do it as
root. Setup a rpm build environment in your home directory

mkdir -p redhat/{BUILD,RPMS/{i386,i686,noarch,x86_64},SOURCES,SPECS,SRPMS}
echo "%_topdir /home/$USER/redhat/" >> .rpmmacros

Now when you do a rpm -ivh somepackage.src.rpm it will install into
your own SOURCES  directory. 

cd redhat/SPECS && rpmbuild -bb somepackage.spec will give you your rpms
under the appropriate arch directory.

You could even create a rpm build user specifically for such things...
