No idea really. I'd be guessing that it's an obscure detail in the way
that 'qmake' calls 'fork'. The initial errors on OSX were along the
lines of:

make[2]: g++: Resource temporarily unavailable
/usr/libexec/gcc/i686-apple-darwin10/4.0.1/as: can't fork a new
process to execute

Searching on those returned a lot of 'old' results. Previous versions
of OSX had a fairly low number of maximum processes per user. I
started fiddling with this, but that's when I noticed that hundreds of
cc1plus processes were being created....

I'll leave that in for the train of thought.

I just tried something that is working on OSX, I suspect FreeBSD will
be the same (I'm running it in a vm and it takes 145 mins to run).

-        MAKEFLAGS="-j '$(JOBS)'" \
+        MAKEFLAGS="-j $(JOBS)" \

It looks like the ' surrounding a number is the problem.
