			<content:encoded><![CDATA[<p><img src="http://blog.vivisectingmedia.com/wp-content/uploads/2008/02/erlang.gif" title="erlang.gif" alt="erlang.gif" align="left" hspace="10" vspace="5" />I have been really interested in Erlang since I first read about it on <a href="http://www.onflex.org/ted/2008/01/why-erlang.php" target="_blank">Ted&#8217;s blog post about &#8220;Why Erlang?&#8221;</a>.  I picked up Joe Armstrong&#8217;s book <a href="http://www.pragprog.com/titles/jaerlang" title="Programming Erlang: Software for a Concurrent World" target="_blank">&#8220;Programming Erlang&#8221;</a> and during the install I about pulled out all my hair.  The issue was that after I ran the <code>sudo make install</code> command after the build completed nothing happened when I called <code>erl</code> from the terminal. Pulling out my Google Kung Fu did nothing. I couldn&#8217;t find anyone that had the same problem with installing Erlang.</p>

<p>The problem was actually not Erlang, but how <code>bash</code> was configured.  The <code>bash</code> client I had for my terminal did not have the path configured for where <code>make</code> was installing the compiled code.  I found this out when I went down the path of trying to install <a href="http://www.macports.org/" target="_blank">MacPorts</a> on my box.  After their installer ran I had the same error in terminal.  At this point I realized it was system configuration issue and not application specific.  Luckily <a href="http://garrickvanburen.com/archive/how-to-install-macports-apache2-rails-mysql-mongrel-and-subversion-on-an-intel-mac" target="_blank">Garrick Van Buren had the same kind of issue with MacPorts</a> and his <code>bash</code> client.  His tip let me to search where the <code>bin</code> directory path was set with the <code>env</code> command and this is what made all the difference.  I moved the built code over to a mapped <code>bin</code> and this fixed the issue.</p>

<p>I wanted to post this in-case anyone else stumbles onto this issue with any install such as Erlang.  Now that it is installed I am off to dig into the new language.</p>
