You do not want to be caught linking to .so files one version too old at some future time. When you build it watch for any new compiler warnings... file bugs on both old and new warnings (with patches if you can). I see that Miredo Version: 1.1.5-2 exists so you should also inspect to see if those changes are important. In general you might expect programs to run one or two releases back. I have run some binary packages a lot longer than that so YMMV. In this case (networking IPV6 tunneling) things could change quicker so stay as current as you can and watch as each new kernel change is delivered. Looking at it you could be ok for a long tome. -- NiftyCluster T o m M i t c h e l l
