title: Libtool think that a "library was moved" but it isn't the case
body: <p>I am currently recompiling gtk+ and dependencies from source (I have no other choices).</p>
  
  <p>All my custom packages are installed in a specific custom point (let's call it <code>/packages</code>) (it can seem odd but this time again, I have no other choices).</p>
  
  <p>When I try to recompile pango, it needs freetype.
  Freetype is already installed in <code>/packages/freetype/2.1.10/amd64-linux</code>  (lib, include ... are in this directory) and the different config path are set (<code>LD_LIBRARY_PATH</code>, <code>LIBRARY_PATH</code>, <code>CPLUS_INCLUDE_PATH</code>, <code>INCLUDE_PATH</code>, <code>PKG_CONFIG_PATH</code>).
  configuration of pango run well. It find freetype and generate the Makefile.
  When I try to make, I get the following error :</p>
  
  <pre><code>libtool: link: warning: library `/packages/freetype/2.1.10/amd64-linux//lib/libfreetype.la' was moved.
  grep: /usr/local/lib/libfreetype.la: No such file or directory
  </code></pre>
  
  <p>libtool has a problem with my lib (but libfreetype.la exists in the directory <code>/packages/freetype/2.1.10/amd64-linux//lib/</code>and there's no problem of access). So libtool try to find it in the "classic places" like <code>/usr/...</code> and don't find it.</p>
  
  <p>At the beginning, I thought that libtool get confused with the two slashes (probably due to an error in the --prefix flag during the compilation of freetype) so I did recompile freetype without the typo but it didn't change anything.</p>
  
  <p>Has anybody an idea to help me ? I have never used libtool in my personnal projects before so I don't know if there's a way to solve this strange behavior... (It's maybe irrelevant but libtool is version 1.5.22)</p>
  
  <p>Thanks in advance.</p>
