Ah well ... I did go back and try a "make buildworld" and in fact I did 
it this way :

root at eris:/usr/src #
root at eris:/usr/src # /usr/bin/time -p make buildworld | tee 
 >>> World build started on Tue Nov 27 09:27:45 UTC 2018

 >>> Rebuilding the temporary build tree
rm -rf /usr/obj/usr/src/powerpc.powerpc64/tmp

objcopy --only-keep-debug ldd32.full ldd32.debug
objcopy --strip-debug --add-gnu-debuglink=ldd32.debug  ldd32.full ldd32

 >>> World build completed on Tue Nov 27 16:48:18 UTC 2018
real 26436.93
user 12547.80
sys 13005.84
root at eris:/usr/src #

So that is offensively slow but a gcc bootstrap is far worse. So no
big deal .. I can handle it.

so .. which comes first ?  Or is this an either or situation or do both?

Right ... only /etc/make.conf exists and it was just a "touch
/etc/make.conf" and nothing else.  I really want CFLAGS set as -O0 and
-g and perhaps a few other options to allow debug to be easy. However
for now getting a working compile is step zero.

What?  How is that possible?  Perhaps you are way out on the road
somewhere and I thank you for the reply. I felt like I was flailing
in the dark here and that is a good description.

I may boot the RC2 DVD and then run dd if=/dev/zero of=/dev/diskname
and wipe out the first block of cylinders on the disk.  Then try a
reinstall. I am baffled why the DVD boots fine and I get four processors
online and the installed on disk image does not.  That should be quite

I may try again wwith an SSD but those are giving no advantage at all.
Even older Patriot SATA 1 compliant 1.5Gbps SSD's are really no better
than a spinning disk.
