Hi Tim,

It's not a compiler flag, it's a make flag.  make -j n will fork off up to
n compilers to do the build.  If you just do "make buildworld" then there
is no parallel compilation.

It used to be that ports had MAKE_JOBS_SAFE in the Makefile to mark that
the port could be built using parallel compiles with the '-j' argument
to make.  It appears that the logic has been switched and now you have
to mark them as MAKE_JOBS_UNSAFE to say that parallel builds shouldn't be
done, indicating that parallel builds are the default now (unless I'm
misreading the code)

You can try putting


into /etc/make.conf to see if that stops the problem on port builds.
Alternatively I think you could do

portmaster -m DISABLE_MAKE_JOBS=yes <other options>

However you'd have to do that each time you run portmaster.  I think


in your .portmasterrc may do the same thing (not tried it).

Note: this is NOT a fix.  If it works, it merely stops the ports builder
from triggering the problem by not doing parallel compiles.  The compiles
will also take longer.
