Yes. --with/without-ofud never worked, anyway (i.e., there was no code that implemented it). Ditto that there was no --with/without-ud.

Yes. Same was true for --with-openib=DIR.

There isn't one.
You're probably thinking of hwloc; hwloc can *use* verbs, but it doesn't *require* verbs. The other 3 (OOB UD, BTL OFUD, BTL openib) all *require* verbs and cannot be built without it.
