Hmm. I'm not sure what's going wrong here.
That symbol is supposed to be defined in the -lmer_rt library, i.e.
in libmer_rt.a or (if you're using shared libraries) libmer_rt.so.

What's the output of the following commands?

	d=/usr/local/mercury-compiler-0.8/lib/mercury/lib/asm_fast.gc
	# or if you're using (t)csh
	# setenv d /usr/local/mercury-compiler-0.8/lib/mercury/lib/asm_fast.gc

	ls -l $d/i386-unknown-freebsd3.0
	nm $d/i386-unknown-freebsd3.0/libmer_rt.a | grep -i grade
	nm $d/i386-unknown-freebsd3.0/libmer_rt.so | grep -i grade
