Where is the apache2 source is installed
<p>I am trying to install the Apache::Registry from cpan. And this gentleman needs the source for apache2, which it could not find. So, it is asking me about its whereabouts. </p>

<pre><code>Enter `q' to stop search
Please tell me where I can find your apache src
 [../apache_x.x/src] 
</code></pre>

<p>So, I installed the apache2 source.</p>

<pre><code>$ sudo apt-get install apache2-dev

<p>Now, I restarted the install for Apache::Registry, but it still could not find the apache2 source. Oh well, needless to say, I had to look for it myself. I search in all directories where this source is expected to be to no avail. So, where is the default location where the apache source should be once install from the the apache2-dev package?</p>

<p>Thank you!</p>
