Upgrading Sudo

Hi all
I am trying to upgrade Sudo on my Redhat Linu 7.0 box. I have obtained the latest version of Sudo (1.6.6) from Sudo. THis is in the form of a src.rpm file. I am confused about installing this. How can I install from a source rpm. It does not upgrade the package when I do a rpm -Uvh <filename> Three files get created when I fo this:
a
/usr/src/redhat/SOURCES/sudo-1.6.5p2.tar.bz2
/usr/src/redhat/SOURCES/sudo-1.6.5p3.patch
/usr/src/redhat/SPEC/sudo.spec

I do not know where to proceed from here. I tried to do rpm -bb /usr/src/redhat/SPEC/sudo.spec. But got the message:
error: failed to build dependencies:
pam-devl is needed bu sudo-1.6.5p2-1.7x.1

Please give me some direction as to where to proceed from here.

Thanks all in advance.

Why don't you get the binary package from a redhat mirror? For example, here:
ftp://ftp.dulug.duke.edu/pub/redhat/linux/updates/7.0/en/os/i386/sudo-1.6.5p2-1.7x.1.i386.rpm

Pick a mirror closer to you if you are not in north america. The list of mirrors is here: Software & Download Center - Red Hat Customer Portal

As far as installing a source rpm, you would need to use the '--rebuild' option. Check the rpm man page for details. In general, its easier to just use the RedHat-provided rpms when possible.
