title: Build m4, autoconf, automake, libtool on unix
body: <p>I'm trying to setup PHP, apache environment on HP-UX server. While install i'm using usual commands of "./configur, make, make install". Here when I'm trying to install PCRE I got an error like follows.</p>
  
  <pre><code>CDPATH="${ZSH_VERSION+.}:" &amp;&amp; cd . &amp;&amp; /bin/bash /home/ubuntu/softwares/m4-1.4.17/build-aux/missing aclocal-1.14 -I m4 /home/ubuntu/softwares/m4-1.4.17/build-aux/missing: line 81: aclocal-1.14: command not found WARNING: 'aclocal-1.14' is missing on your system.
           You should only need it if you modified 'acinclude.m4' or
           'configure.ac' or m4 files included by 'configure.ac'.
           The 'aclocal' program is part of the GNU Automake package:
           &lt;http://www.gnu.org/software/automake&gt;
           It also requires GNU Autoconf, GNU m4 and Perl in order to run:
           &lt;http://www.gnu.org/software/autoconf&gt;
           &lt;http://www.gnu.org/software/m4/&gt;
           &lt;http://www.perl.org/&gt; Makefile:1496: recipe for target 'aclocal.m4' failed make: *** [aclocal.m4] Error 127
  </code></pre>
  
  <p>So I download latest versions of "m4, autoconf and automake" source and try to install using usual make command.</p>
  
  <p>First I tried to install "automake" it through error asking to install "autoconf"
  Then I tried to install autoconf again it ask to install "m4"
  Then I tried to install "m4" now it through the same error above listed.
  So it became a loop of same set of error not letting me to install.</p>
  
  <p>Can any one help me to sort this issues. Please consider this is a HP-UX unix server so don't recommend the famous ubuntu "apt-get install" command or red hat specific commands.</p>
