There are tools that do this, good tools. If you are managing many packages on many systems you should look into Puppet, or RedHat Satellite Server.

To answer the question you asked for random package 'bc':

#!/usr/bin/perl -w

my $package='http://mirror.1000mbps.com/centos/6/os/i386/Packages/bc-1
+.06.95-1.el6.i686.rpm';

my $result=`rpm -q bc`;

if ( $result =~ /not installed/ ) {
  system "rpm -i $package";
}

[download]

RPM does all the heavy lifting here. It can download from a URL and install. Any production script should include error checking. Also RPM itself will fail if that package needs uninstalled dependencies, if you have a version of RHEL that isn't 6, or if you are not running i386 or x86_64.
