awk to check for rpm packages

I have a list of rpm packages... and want to check if the version is equal to or greater than the package in the package list. This is what I have so far... but I would like to add more intelligence to it.

while read line
do
 COUNT=`rpm -qa --qf "%{n}-%{v}-%{r} (%{arch})\n" | grep -c "$line"`
 if [ $COUNT -ge 1 ]
 then
  logMessage "Step #7b - (PASS) $line = $COUNT."
 else
  logError "Step #7b - $line = $COUNT."
 fi
done < rpm_pkgs.txt

rpm_pkgs looks like this:

binutils-2.15.92.0.2-25 (x86_64)
compat-libstdc++-33-3.2.3-47.3 (x86_64)
compat-libstdc++-33-3.2.3-47.3 (i386)
elfutils-libelf-0.97.1-5 (x86_64)
expat-1.95.7-4 (x86_64)
glibc-2.3.4-2.41 (x86_64)
glibc-2.3.4-2.41 (i686)
glibc-common-2.3.4-2.41 (x86_64)
libaio-0.3.105-2 (i386)
libgcc-3.4.6-10 (x86_64)

etc.  

Can someone help with creating an awk statement to check to see if the version on the server is equal to or greater than the version in the rpm_pkgs.txt file?

Thanks!
