adding a message when blocking friendships using Membership plugin

Hey, ok we have implemented the membership plugin on my site, I have three categories Models, Photographer and Recruiters, I don't allow for friendships on all the free memberships accept for when you register as a Model, Now members belonging to the Free Photographers subscription are complaining that the site is broken because all they can see is a red X when they access friends or try and respond to friend requests, My question is, How can I add a message where the red x was stating that "Friendships aren't supported on your current subscription" with maybe a link to take them to the subscription page
