Yes, points to the OP for asking on how to handle it rather than just blindly adding the PPA, which would always be a gamble.
I have the original conky-manager and conkymanager2 (I renamed the 2.X version so both could be installed at once) for the Wheezy-based MEPIS 12 repo, and it's very popular. You can install .7z theme packs into it that allow for all kinds of customized conkys if the user doesn't want to fool around with the conkyrc syntax.
I see we need those rebuilt for the Jessie-based MX 15 repo, for which we have started some heavy development. We'll probably have a public beta next month.
Edit: Here's the packages, built on vanilla Jessie installs in virtual machines: https://copy.com/nPD0H9Y3QVgLTqFu
