title: make fails while installing Valgrind
body: <p>I'm trying to install Valgrind on a Mac with Snow Leopard but am getting an error.  This is what I'm typing into Terminal.</p>
  
  <pre><code>$ curl -O http://valgrind.org/downloads/valgrind-3.8.1.tar.bz2
  $ md5sum valgrind-3.8.1.tar.bz2
  $ tar -xjvf valgrind-3.8.1.tar.bz2
  $ cd valgrind-3.8.1
  $ ./configure
  $ make
  </code></pre>
  
  <p>This is the error I get.</p>
  
  <pre><code>Making all in coregrind
  make[2]: *** No rule to make target `/usr/include/mach/mach_vm.defs', needed by `m_mach/mach_vmUser.c'.  Stop.
  make[1]: *** [all-recursive] Error 1
  make: *** [all] Error 2
  </code></pre>
  
  <p>How can I correct this error?</p>
