I get a build error about the toolchain that I don't think I should be 
getting.  Can anyone lend a hand?

I just built 4.99.31 (from tar files labeled 9/10/07) on box A running 
4.99.19.  My target is box B.

My intent was to not install anything, just build.  (did I just update 
box A and didn't realize what I did?)
    ./build.sh -O /usr/obj -T /usr/tools -D /usr/destdir/ -x -U distribution
    ./build.sh -O /usr/obj -T /usr/tools -D /usr/destdir/ -x -U -u release

I then built my target kernel.
    ./build.sh -O /usr/obj -T /usr/tools -D /usr/destdir/ -x -U -u 
kernel=T600

No errors.  So far, so good.

Box B was running the factory distribution 3.1.

On box B, I NFS mounted all my /usr/src, /usr/xsrc, /usr/obj, 
/usr/tools, /usr/destdir connecting to their source on Box A.

I copied the kernel from box A to B.  Rebooted box B and it worked!

When I tried to install userland, that is when I got my failure.
