Installing Bison from CVS

[Hans Aberg]

When installing Bison from the CVS by:
cvs -d:pserver:address@hidden:/cvsroot/gnulib co gnulib
cvs -d:pserver:address@hidden:/cvsroot/bison co bison
cd bison
./bootstrap --gnulib-srcdir=../gnulib

I get the following error:
./bootstrap: autoconf --force ...
configure.ac:111: warning: AM_INTL_SUBDIR is m4_require'd but not  
m4_defun'd
m4/gettext.m4:362: AM_GNU_GETTEXT is expanded from...
configure.ac:111: the top level
configure:15873: error: possibly undefined macro: AM_INTL_SUBDIR
      If this token and others are legitimate, please use  
m4_pattern_allow.
      See the Autoconf documentation.

What is causing it?

Which is the "official" method to get Bison from the CVS? On
  http://savannah.gnu.org/cvs/?group=bison
it is suggested
  cvs -z3 -d:pserver:address@hidden:/sources/bison  
co bison
followed, I gather, by
  cd bison
  ./bootstrap
Is this right?
