[And this is confirmed by your make.log]

OK, so that isn't the problem.

This appears to be the problem; there is another "libedit", and that
is being used instead of the GRASS library of the same name.

The first instance of the problem is in src/general/init, when
compiling etc/set_data:

gcc
-L/Users/andyagena/Desktop/grass-5_0_0_src_0/grass-5.0.0/src/libes/LIB.powerpc-apple-darwin6.0
-L/sw/lib -o
/Users/andyagena/Desktop/grass-5_0_0_src_0/grass-5.0.0/dist.powerpc-apple-darwin6.0/etc/set_data
OBJ.powerpc-apple-darwin6.0/set_data.o
OBJ.powerpc-apple-darwin6.0/mke_mapset.o
OBJ.powerpc-apple-darwin6.0/mke_loc.o
OBJ.powerpc-apple-darwin6.0/chk_dbase.o
OBJ.powerpc-apple-darwin6.0/other.o -ledit -lgis -lvask -lncurses
-ltermcap -lz

This is presumably picking up libedit.dylib instead of GRASS'
libedit.a.

I had thought that the fact that the switch:

-L/Users/andyagena/Desktop/grass-5_0_0_src_0/grass-5.0.0/src/libes/LIB.powerpc-apple-darwin6.0

came first would ensure that any libraries found there would take
precedence, but obviously not.

It may be that the linker prefers *.dylib to *.a, regardless of
location. In which case, the only solution would be to change the
name. Try changing the corresponding lines in src/CMD/generic/make.mid
from:

	DEPEDITLIB     = $(LIBDIR)/libedit.a
	EDITLIB        = -ledit
to:
	DEPEDITLIB     = $(LIBDIR)/libgedit.a
	EDITLIB        = -lgedit

Then re-compile (you might need to run "make clean" first).

If this fixes the problem, then I really need to find out more about
the details of how linking works on MacOS X. Simply hoping that name
clashes don't occur isn't really a solution.
