Good I was hoping it was. I can see the answer to this is that I
shouldn't be building on one machine then installing on another. The
build machine should install the files. That just means I have to do
weird nfs mounts that I didn't want to do. But I'll explain what I'm
doing now.

My setup:
I have an nfs share /usr/world that contains src,obj,ports
/usr/src is symlinked to /usr/world/src
/usr/obj is symlinked to /usr/world/obj

I have 2 machines like this, Chaotic (800Mhz i386) and Solar (260Mhz
sparc). Here is exactly what I'm doing:

chaotic:/usr/src# make TARGET_ARCH=sparc64 buildworld
This completes without error and the output can be seen here:
http://chaotic.oz.org/other/bsd/buildworld.out.gz (414k gz, 6.3meg txt)

solar:/usr/src# make TARGET_ARCH=sparc64 MAKEOBJDIRPREFIX=/usr/obj/sparc64 installworld

This is where I get the install not found error. I also have to add the
MAKEOBJDIRPREFIX so that it can find the build directory. By default it
looks in /usr/obj/ but when you do TARGET_ARCH=sparc64 on
i386 machine it puts it in /usr/obj/sparc64/ From the looks of the only 
the i386 legacy binaries are compiled (the things in 
/usr/obj/.../src/<platform>/legacy/* so it puts that in the path for 
installing and doesn't work.

Output here:
http://chaotic.oz.org/other/bsd/installworld.out.gz (1k gz, 5k txt)

Anyway there's my error messages..

Simon
