Unable to install software using brew install
The problem is that gnu have moved the file so you do not get the source of automake when homebrew downloads it.

If you download the file http://ftpmirror.gnu.org/automake/automake-1.14.tar.gz you get

&lt;!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"&gt;
&lt;html&gt;&lt;head&gt;
&lt;title&gt;302 Found&lt;/title&gt;
&lt;/head&gt;&lt;body&gt;
&lt;h1&gt;Found&lt;/h1&gt;
&lt;p&gt;The document has moved &lt;a href="http://ftp.heanet.ie/mirrors/gnu/automake/automake-1.14.tar.gz"&gt;here&lt;/a&gt;.&lt;/p&gt;
&lt;hr&gt;
&lt;address&gt;Apache/2.2.16 (Debian) Server at ftpmirror.gnu.org Port 80&lt;/address&gt;
&lt;/body&gt;&lt;/html&gt;
