Can't speak officially for the VT folks, but it looks like the following
bits in ompi/vt/vt/acinclude.m4 needs to list SPARC and Alpha (maybe
ARM?) along side MIPS as gettimeofday() platforms. Alternatively
(perhaps preferred) one should turn this around to explicitly list the
platforms that *do* have cycle counter support (ppc64, ppc32, ia64, x86
IIRC) rather than listing those that don't.
