That's not what firstname.lastname@example.org (sorry don't know the name) suggested:

I have managed to build things, sort of. But it was far from automatic.

Several, actually (this is for an arm32 build, but I don't think it is any
way port specific):
1) Since it was a first time build, the last thing I wanted was to blow
away my known working installation until I was happy that I could get a
-current to work. A wise choice, since I still haven't managed to do
this, though this is probably as much due to lack of time on my part as to
real problems now.
2) There is no (single) document that describes building the NetBSD source
3) It therefore took a while to find the DESTDIR variable.
3a) The fact that you can't set DESTDIR in /etc/mk.conf (or $MAKECONF)
because that file isn't always included before DESTDIR is first used -- so
you have to set it on the command line.
4) I wanted to put the install for the build onto a spare disk (that way I
could then boot from that disk to see if it all worked -- see 1 above).
To do this I mounted the empty disk on /mnt and set DESTDIR to that.
5) The fact that the new disk had no directory structure on it immediately
caused "make includes" to barf. Had to spend an eternity looking for this
one (eventually found the "distribution" rule in src/etc/Makefile -- why
isn't this mirrored into the top-level makefile with a special rule?).
6) The fact that make picks up /usr/share/mk implicitly, which does not
contain all the needed rules for building the -current sources. However,
the new rules (in src/share/mk) invoke commands with options that don't
exist in the 1.3 release -- the biggest culprits are ld when building
shared libraries and lint.
7) The fact that you keep having to install parts that have just been
built before you can build the next stage. This means that the build can
only be done as a single step if you are root. I really want to do the
compilation as a non-root task and then finally do an install as root once
the compiling is complete.
8) The fact that when I started all this, my installation was on a SCSI
disk with an Acorn SCSI podule card (read no DMA and a maximum throughput
of around 600Kb/s) -- OK this isn't a fault I expect anyone to fix :-(
There have been other problems, but they were largely self-inflicted --
such as trying to use a development version of egcs sucked directly from
the Cygnus repository (the main reason I want to do all of this is to test
out the compiler).
I suspect that a large number of the above would have to be fixed to make
a cross-build system work cleanly.
