  <p>When I try, <code>sudo apt-get install libpulse-dev</code>, I get the following error:</p>
  
  <p>The following packages have unmet dependencies:
   libpulse-dev : Depends: libglib2.0-dev but it is not going to be installed
  E: Unable to correct problems, you have held broken packages.</p>
  
  <p>Thogh, I tried installing with 'aptitude', libpulse-dev gets installed but the error for textract with aptitude is  that it is not able to locate that package. </p>
