If you have sfDoctrineGuard 5.x then none of these plugins' packages will work out of the box with this version.
I know that sfDoctrineApply changed their approach, so they will extend the User object instead of profile one in next versions. As for sfForked, it still be providing separate object for profile.
As for compatibility with sfDoctrineGuard 5.x I'm working on it on this branch on github: http://github.com/fizyk/sfForkedDoctrin ... rineGuard5
if you'd like to give it a try.
