title: How to solve the error " missing required header GL/gl.h" while installing the Package mvoutlier in R?
body: <p>I am trying to install the <code>package mvoutlier</code> but following error occurs during installation:</p>
  
  <pre><code>install.packages("mvoutlier")
  configure: error: missing required header GL/gl.h 
  ERROR: configuration failed for package ‘rgl’
  * removing ‘/home/sam/R/x86_64-pc-linux-gnu-library /2.15/rgl’
  ERROR: dependency ‘rgl’ is not available for package ‘compositions’
  * removing ‘/home/sam/R/x86_64-pc-linux-gnu-library/2.15/compositions’
  ERROR: dependency ‘compositions’ is not available for package ‘mvoutlier’
  * removing ‘/home/sam/R/x86_64-pc-linux-gnu-library/2.15/mvoutlier’
  </code></pre>
  
  <p>After that I have install the rgl package successfully, then I tried to install the compositions package then the again same error occurs. Then I have again tried to install the mvoutlier package the same error occurs.</p>
  
  <p>Can anyone let me know how I can resolve this problem. Thanking you in advance.</p>
