Building lustre 2.8 client with mpss 3.8.1

Hi,
I'm trying to follow steps similar to those for mpss-3.3/3.4 that are posted in the forum. I need IB (ofed) support.

For mpss-3.8.1 there is a problem I'm running into - the ofed-driver-devel rpm or file is not included. How do I get it for 3.8.1 or build it with the included ofed-driver source rpm.

Thanks in advance
