That should be your hint that the problem is not in autoconf, but in
your setup.

But if you type '/usr/local/bin/autoconf -V', you should get the
just-installed version.  That is, your PATH is requesting that
'autoconf' forwards to '/usr/bin/autoconf', and you did not replace that
file when installing your self-built version.

Yep, that is indeed your problem.  Your setup is atypical (most distros
stick /usr/local/bin/ before /usr/bin/ in their default setup of $PATH,
so you must have customized things differently).  You can also force
your self-built versions to install into /usr/bin instead of
/usr/local/bin by passing appropriate options to ./configure, although I
would not recommend doing that (as it tends to make getting support from
your distro much more difficult).

Apologies for my typo, I meant autoconf.  But the point remains: it is
your atypical choice of PATH that is letting a path lookup for autoconf
find your old distro version instead of your just-built version, and if
you want to find your just-built version without an absolute file name,
then you need to fix your PATH.
