What exactly went wrong?  Setting DESTDIR is the correct way to do this
sort of thing.  You only need to set it when running the installworld or
installkernel steps though -- there's nothing that gets compiled into
/usr/obj which prevents you from installing into a different than normal
tree.

I use this sort of construct frequently for updating jails, or when
managing boot environments.

For each different DESTDIR, just repeat the installworld, installkernel,
check-old, delete-old* steps setting DESTDIR=/some/where
on the make command line.

The equivalent for mergemaster is to add '-D /some/where' to the
commandline.
