Change libtool used in command line I followed this post to install automake, autoconf and libtool.

When I check automake and autoconf versions they look fine. However, when I check libtool's version I get the following

$ libtool --version
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: unknown option character `-' in: --version


however if I run libtool from install folder I get

$ /usr/local/libtool/bin/libtool --version
libtool (GNU libtool) 2.4.2 Written by Gordon Matzigkeit &lt;gord@gnu.ai.mit.edu&gt;, 1996


So I think there is a version of libtool already installed with OS X. Is there a way to change it so that when I execute libtool it calls the one on /usr/local/libtool/bin?
Unless your $PATH is different than normal, you could solve that with a sym link of the tool you want.

$echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin


Then if the libtool you want to run first is /usr/local/libtool/bin/libtool then a quick

sudo ln -s /usr/local/libtool/bin/libtool /usr/local/bin


At that point, you might have to restart your shell or rehash or hash -r in bash to get the libtool from /usr/local/bin to be preferred.
