title: Cannot find .a static library files after building boost with macports, I only have dylib
body: <p>Using Xcode 7.1...</p>
  
  <p>Built using command <code>sudo port install boost +universal</code></p>
  
  <p>I am under the impression that if I want to distribute my software, .dylib files will be required for every user because dylib is a dynamic library, while .a will be statically linked and so it will be embedded in the final product. Is this true? If so, how do I get .a files?</p>
  
  <p>I'm trying to make use of regex and filesystem libraries.</p>
