It is the non-declarative part of libtool.  When installed libtool contains the
text of ltmain.sh.  Please RTFM for more details -- unfortunately autotools 
still
requires a ton of intermediate files, which are confusing enough that I won't
try to explain again in a list post when there is already much better 
documentation
online.

Are you sure that's the version you actually installed, and not an older
installation?  Check the timestamp on the file and the version to be sure.

  $ ls -l /usr/local/bin/libtool
  $ /usr/local/bin/libtool --version

What is your path set to?  Maybe you have another libtool nearer the beginning 
of
your path than the one in /usr/local/bin?

  $ echo $PATH

Also don't forget to tell your shell to rebuild the command hash, otherwise it 
will
continue to run the libtool it found and hashed the path to before your newly
installed libtool arrived.

  $ hash -r # assuming you're using bash or zsh

It seems like you might have better luck using your system package manager to
upgrade to a non-ancient libtool rather than trying to install one from scratch
by yourself.  Does your system come with apt or yum or similar?

HTH,
