Check for unversioned autoconf
This is probably a better issue for my distro, but while it has old versions of tools like autoconf, it installs it as just
autoconf rather than
autoconf-2.64. The distro has ways of accommodating multiple versions of the same name, so it's not overwriting anything. As it stands right now, I just had a small edit to setup.sh, but checking the version based on
--version might require a bit of logic.
