Linkmachine Support in MODx?

Has anyone out there used LinkMachine? It’s a simple PHP app for exchanging links with other sites, used to boost SEO ratings. I’m porting a static site over to MODx and I wanted LinkMachine to come along for the ride, but it doesn’t seem too happy about it. Has anyone done this before? I suppose I could write my own form to manage links, but it’s a shame if I can’t make use of existing code.

Thanks.
