Please note, FreeBSD 4.7 falls outside the FreeBSD versions I listed.

Why?  It is operating differently.  Do you expect to see any difference
in behavior between a UP or SMP kernel?

Why doesn't all the extra output of:

  ===> gnu/usr.bin/gperf (obj,depend,all,install)
  ===> gnu/usr.bin/gperf/doc (obj)
  ===> gnu/usr.bin/gperf/doc (depend)
  ===> gnu/usr.bin/gperf/doc (all)

bother you?  I expect the "make obj" or "make depend" step to just happen
nicely and quietly.  But instead its there.

Eh?  Software has 100,000's of behavior changes between versions.

I don't believe it will happen - I've had patches to add -j to ports
build for a long time, there has been very minimal interest in them.
The answer there has aways to be build multiple ports at the same time.
And so many ports aren't tested for '-j' builds it is naive to think the
vast majority of ports would build with '-j'.  (my patch was an opt-in
for large things like gcc)
