But of course - we can cook your breakfast as well ;).
You can explicitly disable a component using the --enable-mca-no-
build=NAME. I know the syntax is a bit wonky, but Autoconf doesn't
make this easy :(. Since you want to disable Open IB, you might do
./configure [rest of options] --enable-mca-no-build=bml-openib
Does something bad happen if you try to build with the Open IB
component enabled? If so, could you let us know what happens? Galen
and I are trying to make sure we have all the BTL configure scripts
tightened up before we release to the world. If it's just something
about your test environment, no biggie - just want to make sure we
don't have a real problem.
Since you only are interested in the MVAPI port and therefore not at
all interested in the TEG PML (the older generation of communication
interface), you can build with:
./configure [rest of options] --enable-mca-no-build=bml-openib,pml-
which will cause the older generation PMLs to not be built. I think
this is probably going to make life easiest on you.

I think that most of your problems will go away once you start using
the OB1 PML and therefore actually start using the MVAPI interface.
I know that both Galen and I have been running a slightly modified
copy of the Intel test suite against the MVAPI driver on a fairly
regular basis. There are one or two minor datatype issues that still
need to be worked out, but we should pass all the point to point tests.
Hope this helps,
