title: Install gnuplot 5.0.1 on OSX
body: <p>I downloaded the source files for gnuplot 5.0.1 (gnuplot-5.0.1.tar.gz) from the <a href="http://sourceforge.net/projects/gnuplot/files/gnuplot/5.0.1/">source forge page</a>. I also installed the Command Line Tools on my OS X 10.7.5 so that I have <code>gcc</code> and <code>make</code> in the <code>/usr/bin</code> folder. </p>
  
  <p>I followed the installation instructions found in <code>INSTALL.gnu</code> file of the tarball: I ran the <code>configure</code> file and typed <code>make</code>, <code>make check</code>, <code>make install</code>, and <code>make clean</code>. With these commands, <code>gnuplot</code> is located in <code>/usr/local/bin/</code>.</p>
  
  <p>The <code>make check</code> command outputs a lot of lines in the shell before testing many gnuplot scripts. I could actually visualize the plots and I thought "great, it works". So I opened a new terminal shell and typed <code>gnuplot</code> to begin using it (the terminal is automatically set to qt). A simple <code>plot sin(x)</code> fails. Gnuplot returns these messages : </p>
