I need to do the equivalent of  "cd /usr/src/cddl/usr.sbin/dtrace;
make DESTDIR=/mumble all install"

but it pulls in libraries from the base system, which differ slightly
from those in the source tree.

How can I force it to use /mumble2/include and /mumble2/lib instead of / ?

I can pre-populate /mumble2 using "make buildworld", "make libraries",
and "make includes" but
I need to be able to do selective builds of just subdirectories after
that..  I haven't spotted the right way of forcing the use of the
"--system_root /mumble2" option in the compiles.

I know we do it in 'buildworld' is there a more generic way?

I have been looking in the .mk files but I haven't spotted it so far.

An option woudl be a way to 'enter' a buildworld and just rebuild or
reinstall small specified parts of it.
Unfortunately at the moment I see no option other than a lot of
WITHOUT_XXX and 'build everything'.

The 'buildenv' target does the "enter a buildworld" thing.  Just "make
buildenv" and you get a shell with all the environment variables set up
for doing builds (or cross-builds if you set TARGET_ARCH) within that
source tree.  If csh isn't your favorite shell, set BUILDENV_SHELL in
your environment.  There's also a "buildenvvars" target that will let
you capture the environment you need so that you can use it within your
own build scripts without needing an interactive shell.

oh man that is just what I'm looking for
Is there a single command for populating the  buildenv resources?
i.e. to compile and install all the tools and libraries (and includes
etc) (into /usr/obj/usr/src/tmp... )
"make toolchain" should do that.  There's also kernel-toolchain for
building just the kernel; I think the only difference between the two is
that kernel-toolchain doesn't build userland includes and libs.
excellent !
