Very likely, my first thought after things compiled without it, was some 
solaris admin would probably have said, "Makefiles written by people not 
used to compile on boxes with >20 CPUs."

Strange, thought I had looked there "/usr/lib/rpm/i686-linux/macros", 
it's all there:

%_smp_mflags %([ -z "$RPM_BUILD_NCPUS" ] \\\
         && RPM_BUILD_NCPUS="`/usr/bin/getconf _NPROCESSORS_ONLN`"; \\\
         [ "$RPM_BUILD_NCPUS" -gt 1 ] && echo "-j$RPM_BUILD_NCPUS")

You are 100% right with your assumption!

Yep, even if it's not a big issue to me, saw from the list that it's 
already outdated, will grab the latest stable version asap and rebuild.

Big thx for your yum repositories!
