To update everyone: there was much more discussion about this off-list. :-)
We decided to do the following:
1. The name --with-verbs seems better than --with-openfabrics, if for no other reason
than the name "openfabrics" encompasses more things than we intend with this
name (e.g., udapl, psm, etc.).
2. There is a definite problem that needs to be fixed, but it is only partially
related to the renaming. Basically: the proposed option renaming is occurring
opportunistically with this bug fix.
3. We are *not* renaming the openib BTL at this time. It would be great if
someone would do this in the future, hint hint!
4. The behavior of --with[out]-verbs is as was described in a prior mail:
- if --with-verbs is specified, all 3 verbs-based components must succeed
- if --without-verbs is specified, all 4 verbs-based components will not
build
- if --with-verbs=DIR is specified, all 3 verbs-based components must
succeed and will use DIR to find verbs headers and libraries
What does it mean that "all 3 verbs-based components must succeed"?
Does that mean you cannot specify --with-verbs=DIR --with-openib
--without-ofud?
Does it mean that if you specify --with-verbs=DIR and some other
dependency is not found for openib btl that the configure fails?
What is the 4th verbs-based component this is not built when one
specifies --without-verbs.
--td
5. The new collectives / non-blocking collectives will likely revise some more
configury in this area when it comes in mid/late next week, because a bunch of
verbs stuff moved out of the openib BTL and into common. Pasha and I will
revisit this when all that stuff is merged in next week.
6. I'll be committing the current --with-verbs stuff right now in order to fix
the bug that Brian is running in to.

About naming - I would agree with Terry, it makes sense to name it after network API used
for this btl - "verbs" (it is not obverts).
I don't think that "verbs" is terrible, but I think that "openfabrics" has more
user-level recognition.
For example, if you ask a customer what kind of network stack they have installed on their machine,
they'll say "I have OFED installed". They won't say "I have the verbs stack
installed."
