title: How to find where older version of GLIB has been installed?
body: <p>I am trying to install <code>atk-2.4.0</code> and I get the error:</p>
  
  <pre><code> 'pkg-config --modversion glib-2.0' returned 2.32.3, but GLIB (2.26.1)
  *** was found!
  </code></pre>
  
  <p>I also tried updating <code>PKG_CONFIG_PATH</code> to include the path of <code>glib-2.0.pc</code> but still same error appears. Could anyone help me how to find where 2.26.1 was installed I am relatively new to Ununtu? Thanks.</p>
