Have a PPC profile that messes w/ the module list? (Claim on the profiles doc page is that its possible[1]). Exclude hbase-protocol* modules if os finds that the platform is PPC? (Activating a profile based off os is common usage). Have the PPC profile depend on published versions of these jars? Would something like this do Josh?
