I get the same error on all my machines.  I re-installed one of my crash
boxes from scratch and built the latest versions of the ports that ezm3
depends on, but no luck.  It looks like the Makefile in FBSD_SPARC64/gcc
gets sucked in when building FBSD_SPARC64/gcc/intl due to being a subdir,
which is where it could be getting STAGE_PREFIX from.  I got ezm3 it to
build with this patch, and the resulting cvsup binary seems to work fine,
but it may just be due to removing stuff from the environment as you
describe.
