I think some of the problems here could be fixed by noting what tools
are required by gnulib developers.  There is no such section in the
gnulib README or gnulib.texi, or did I miss it?  I re-installed the
gnulib daily build bot yesterday, and I had to install these:

c compiler (gcc)
autoconf: minimum version?  recommended version?
automake:
libtool:
gettext:
bison:
gperf: at least 3.x?

More?  'makeinfo'?

I suggest adding this to the top-level README:

 to join the autotools-announce mailing list to be advised of such
 changes.
 
+Required Tools
+==============
+
+Developers using gnulib are required to have certain tools available,
+here is a probably incomplete list that may nevertheless help you to
+get all tools installed before using gnulib.

+c compiler
+sed
+awk
+m4
+autoconf
+automake

+bison
+gperf: version 3.x or later
