title: Composer - extension iconv is missing
body: <p>I'm running Manjaro linux and I have installed apache 2.4.10-1 with php 5.5.15-1 and php-composer 1.0.0.alpha8.458-1.</p>
  
  <p>I want to download project with composer by this command</p>
  
  <pre><code>composer create-project nette/sandbox TaskManager
  </code></pre>
  
  <p>but I'm getting error with ext-iconv</p>
  
  <pre><code>- nette/neon v2.2.1 requires ext-iconv * -&gt; the requested PHP extension iconv is missing from your system.
  - nette/nette v2.2.0 requires ext-iconv * -&gt; the requested PHP extension iconv is missing from your system.
  </code></pre>
  
  <p>But in my php.ini i have enabled iconv extension</p>
  
  <pre><code>extension=iconv.so
  .
  .
  [iconv]
  iconv.input_encoding = ISO-8859-1
  iconv.internal_encoding = ISO-8859-1
  iconv.output_encoding = ISO-8859-1
  </code></pre>
  
  <p>In my php scripts I can use iconv function without any problem.</p>
  
  <p>When I run php -m i see iconv in list with other modules</p>
  
  <p>Any idea where could be problem?</p>
  
  <p><strong>Edit</strong>:
  When I run php -i from cli, I got this:</p>
  
  <pre><code>Configuration File (php.ini) Path =&gt; /etc/php
  Loaded Configuration File =&gt; /etc/php/php.ini
  Scan this dir for additional .ini files =&gt; /etc/php/conf.d
  Additional .ini files parsed =&gt; (none)
  </code></pre>
  
  <p>And in this config file is iconv enabled. </p>
  
  <p>Even when I run</p>
  
  <pre><code>php -d error_reporting=E_ALL -r 'echo iconv("UTF-8", "ASCII//TRANSLIT", "Žluťoučký kůň\n");'
  </code></pre>
  
  <p>it executes properly and prints "Zlutoucky kun".</p>
