title: valgrind no such file or directory
body: <p>I just installed valgrind from <code>apt-get</code> and it is installed to <code>/usr/bin/valgrind</code> according to <code>which</code>.  However...</p>
  
  <pre><code>$ valgrind
  bash: /usr/local/bin/valgrind: No such file or directory
  </code></pre>
  
  <p>What is happening here?</p>
  
  <pre><code>$ /usr/bin/valgrind 
  valgrind: no program specified
  valgrind: Use --help for more information.
  </code></pre>
  
  <p>Also... valgrind won't run when a  file is provided... </p>
  
  <pre><code>$ /usr/bin/valgrind ex3
  valgrind: ex3: command not found
  </code></pre>
  
  <p>EDIT:
  I have no aliases applicable to valgrind.  The file in <code>/usr/bin/valgrind</code> is not a symbolic link.  </p>
  
  <p>However, running <code>/usr/bin/valgrind ./ex3</code> does run correctly.</p>
