I understand that. I am irritated (only a little bit) by the fact that 
MIME-Base64 is not newer in 5.3. It shows the same version at least 
(3.07). On CPAN there is 3.07 dating from 2005. I could not find a newer 
one. But back to rpm. Maybe you can add a Version to Requirement:

Requires: perl(MIME::Base64) >= X.XX

And here is a check for centos version:

# check centos version and set macro
%{!?old_ver: %define old_ver %(if test `awk '{print $3}' /etc/redhat-
release|cut -d'.' -f2` -lt 3 ; then echo "1"; else echo "0"; fi)}

%if %{old_ver} == 1
do something
do something complete different or not

(i am sure this could be done better, more elegant, etc...)

best regards,
