Something strange is happening.  with --pretend, it seems that the blockage is gone, however, without it, I still get blockage:

burn openib-userspace # USE=rdma emerge -uDpv openib-mvapich2

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] sys-cluster/openib-mvapich2-1.0.1  USE="rdma threads -debug -large-cluster -medium-cluster" 0 kB [1]

Total: 1 package (1 new), Size of downloads: 0 kB
Portage tree and overlays:
 [0] /usr/portage
 [1] /usr/portage/local/layman/science
burn openib-userspace # USE=rdma emerge openib-mvapich2
Calculating dependencies... done!
[ebuild  N    ] sys-cluster/openib-mvapich2-1.0.1  USE="rdma threads -debug -large-cluster -medium-cluster"
[blocks B     ] sys-cluster/openib-mvapich2 (is blocking sys-cluster/openib-userspace-1.2.5.1-r1 )

 * Error: The above package list contains packages which cannot be

My bad.
Fixed it.  Update your overlay.  You might have to re-emerge
openib-userspace.  If so, sorry for the inconvenience.
