title: Error installing control v3.0.0 package on El Capitan for Octave
body: <p>I recently installed Octave using the binary installer found on this site: <a href="http://wiki.octave.org/Octave_for_MacOS_X" rel="nofollow noreferrer">http://wiki.octave.org/Octave_for_MacOS_X</a></p>
  
  <p>I then tried to install the control package using 'pkg install -forge control' but it gave me the error 'pkg: error running `make' for the control package.'. I have gone through most of the threads regarding this error but with no success. </p>
  
  <p>I then tried to use MacPorts to install the control package, I followed the instructions on the wiki page above with some help from this thread: <a href="https://stackoverflow.com/questions/24265952/installing-general-package-in-octave-has-error">Installing general package in octave has error</a>. I believe I succeeded installing the packages because I can see them in the folder tree for Octave and MacPorts says it is installed when using the console. </p>
  
  <p>The problem is that when i run some code in Octave it cannot build as it doesn't know that I have installed any additional packages. Using 'pkg list' in Octave it says that no additional packages installed. I feel like I need to link the two together but I don't know how?</p>
  
  <p>I'll happily explain more if I need to and I hope you can help me out.</p>
  
  <p>Many Thanks,</p>
  
  <p>Sam.</p>
