title: Can't find nor install mysql_config
body: <p>I get this error from Inspircd</p>
  
  <pre><code>Can't exec "mysql_config": No such file or directory at /home/alpha/inspircd-2.0.19/make/utilities.pm line 392, &lt;FLAGS&gt; line 37.
  
  
  Make sure you have pkg-config installed
  
  In the case of gnutls configuration errors on debian,
  Ubuntu, etc, you should ensure that you have installed
  gnutls-bin as well as libgnutls-dev and libgnutls.

  <p>I've been looking all over the internet trying to find out how to remove the errors.</p>
  
  <p>I have read multiple threads but no luck. I know I need the libmysqlclient-dev package but I can't for the life of me get it installed.</p>
  
  <p>I run</p>
  
  <pre><code>sudo apt-get install libmysqlclient-dev
  </code></pre>
  
  <p>Also tried cleaning, "-f" and so on but I still get the error.</p>
  
  <pre><code>The following packages have unmet dependencies:
  libmysqlclient-dev : Depends: libmysqlclient18 (= 5.5.40-0ubuntu1) but 5.5.41-0ubuntu0.14.04.1 is to be installed
