Building gnu rcs from git

[nn6eumtr]

I've been trying to build rcs from the git repository. I wasn't able to 
find any instructions, so its been trail and error. I have something 
that works, but not out of the box. The steps I am following are:

        git clone git://git.savannah.gnu.org/rcs.git
        cd rcs
        git submodule add git://git.savannah.gnu.org/gnulib.git
        PATH=$PATH:~/rcs/gnulib/
        sh autogen.sh

And the autogen.sh blows up with this error:

	gnulib-tool: option --conditional-dependencies is not supported with 
--with-tests
        + autoreconf --install --symlink
        sh: 1: build-aux/git-version-gen: not found
	configure.ac:26: error: AC_INIT should be called with package and 
version arguments
        /usr/share/aclocal-1.11/init.m4:26: AM_INIT_AUTOMAKE is expanded from...
        configure.ac:26: the top level
        autom4te: /usr/bin/m4 failed with exit status: 1
        aclocal: /usr/bin/autom4te failed with exit status: 1
        autoreconf: aclocal failed with exit status: 1

And I've been able to get around it by running this:

        gnulib-tool --update --no-conditional-dependencies
        sh autogen.sh

Which does die with this error:

        + actually build-aux/missing
        + gnulib-tool --copy-file build-aux/missing
	/home/xxx/rcs/gnulib//gnulib-tool: *** file 
/home/xxx/rcs/gnulib//build-aux/missing not found
        /home/xxx/rcs/gnulib//gnulib-tool: *** Stop.

But not before producing a working configure script.
