`configure' and `make/bison' build issues

[vy]

Hello.

I've been getting cvs updates of the coreutils file set to build with
a view to eventually adding documentation in info and manpage format.

I've not ever built coreutils successfully on my Mac os x 10.4.6
computer. Previously I could get past the `configure' stage, at the
`make' stage the building process would stop on this instruction
`bison -y getdate.y', ie.

roamantic:~/continuing/_study/coreutils/lib vy$ bison -y getdate.y
getdate.y:215: unrecognized: %parse_param
getdate.y:215:    Skipping to next %
getdate.y:216: unrecognized: %lex_param
getdate.y:216:    Skipping to next %

Now, I am having trouble with

roamantic:~/continuing/_study/coreutils vy$ ./configure
--prefix=/Users/vy/local --exec-prefix=/Users/vy/local/ppc
./configure: line 9: =======: command not found
./configure: line 12: syntax error near unexpected token `>>'
./configure: line 12: `>>>>>>> 1.277'

I suppose the configure issue is transient, any ideas about the
make/bison issue? I have begun to read the bison infopages to get a
grip.
