title: /usr/bin/ld: cannot find -lboost_system-mt
body: <p>I recently upgraded from boost 1.40 to 1.45 by removing the previous boost directory completely, downloading the 1.45 sources and rebuilding the libraries I wanted. I then installed the libs using bjam install.</p>
  
  <p>Nothing else has changed on my machine, yet, now when I am building my C++ program, I get the following link error:</p>
  
  <pre><code>/usr/bin/ld: cannot find -lboost_system-mt
  </code></pre>
  
  <p>I searched and the file really does not exist. It seems that the mt libraries are no longer part of the library - or am I missing something?</p>
  
  <p>How may I resolve this?</p>
