Hello! I need to install MIME::Base64::URLSafe in my Centos-7 perl distribution. It is not found in repositories, but I found opt-perl-522-MIME-Base64-URLSafe in google . I tried to install it, it demands another opt-perl-522 modules and other modules demands yet another opt-perl-522 modules. It seems to me that opt-perl it is another branch of perl which I have to install separately from my usual perl-5.16. Strangely for me I could not find any explanation in google about opt-perl. Please, clear me situation with this. And are there ways to avoid this MIME::Base64::URLSafe.
