There was a workaround in the nuke forums see the link below.

Simple way to make WowRoster work as a module in PhP-Nuke[/url]
I want to keep my standalone roster install, but have it open in a df module. I was able to accoplish this with nuke thanks to the above thread. Would this be possible in DF? There are compatability issues with addons for WowrosterDF and it is best for me to keep the standalone install to ensure I have access to the greatest amount of addons.
