title: fatal error: 'gtk/gtk.h' file not found
body: <p>So I'm trying to install Gtk-Perl-0.7000 from <a href="http://search.cpan.org/dist/Gtk-Perl/" rel="nofollow">http://search.cpan.org/dist/Gtk-Perl/</a> on a mac</p>
  
  <p>I already successfully followed the steps to instal gtk+ at <a href="http://www.gtk.org/" rel="nofollow">http://www.gtk.org/</a></p>
  
  <p>when I run the Makefile.pl from Gtk-Perl-0.7000 it gives me:</p>
  
  <pre><code>gtkvertmp.c:3:10: fatal error: 'gtk/gtk.h' file not found
  #include &lt;gtk/gtk.h&gt;
           ^
  1 error generated.
  Unable to find  Gtk version...
  Invoking gendefs.pl with [].
  Please wait, this may take a moment...
  gtktypexp.c:1:10: fatal error: 'gtk/gtktypeutils.h' file not found
  #include &lt;gtk/gtktypeutils.h&gt;
           ^
  1 error generated.
  </code></pre>
  
  <p>I have:</p>
  
  <pre><code>echo $PKG_CONFIG_PATH
  :/Users/one/gtk/source/gtk+-2.24.16/gtk:/Users/one/gtk/inst/include/gtk-2.0/gtk:/Users/one/gtk/inst/lib/pkgconfig
  </code></pre>
  
  <p>I do have the gtk.h file in my system. I've searched online but haven't gotten Gtk-Perl to compile.</p>
