error when update autoconf2.64

I got the same issue with 2 servers when ./build update_versions

GNU M4 that supports accurate traces... configure: no acceptable m4 could be found in $Path
GNU M4 1.4.6 or later is required; 1.4.13 is recommend
Done. Trying to make autoconf...
cp "/../gnulib/build-aux/announce-gen ./build-aux
cp: canot stat `/../gnulib/build-aux/announce-gen': No such file or directory
make: *** [gnulib-update] Error 1
*** The make has failed, do you want to try to make again (y,n):

Any help?
Thanks

Yea, ran yum update before custombuild...

Wonder if smtalk saw this thread...

Should we have to build gnu-m4 latest from the source?

Anyone tried?

hi type :
and try again to rebuild autoconf

Thanks, this did it:

wget http://ftp.gnu.org/gnu/m4/m4-latest.tar.gz
tar zxvf m4*
cd m4*
./configure
make
make install
