I do not recommend that you use a pre-compiled lsof binary. It is better that you compile lsof for yourself from the distributed sources. But if you can't compile lsof, this set of directory branches contains some lsof binaries. They have been compiled on my test hosts, so you should be careful in using them, since they may not match your Unix dialect version or machine architecture. I try to keep these binaries up to date, but the limitations of time, remembering to do it, and access to some platforms prevent me from being completely faithful to that goal.
All binaries are gzip'd.
The path name includes the lsof revision number. Please read them. None of the binaries has been compiled for an AFS configuration. Using lsof's -h option will tell you the state of its security mode. Lsof requires special permission modes and ownerships to allow it to access protected resources.
