One almost never has the correct versions of autotools pre-installed.
The distros tend to ship something close to the latest version that
was available at the time, and it rarely matches the version that
we are expected to use for each project. The only way I've found to
have the correct version was to build the various versions myself,
and update the PATH accordingly each time I need a set. More effort
than "it-just-works(tm)", but it's really not that bad. We don't change
the auto-tools versions all that often, and building those tools
just takes a few minutes each.

So, my recommendation if you want to control the pace at which this
is fixed, is to build your own set of auto-tools. On my end, I don't
think I'll have much time during the coming weeks, unfortunately.
