title: GCC 4.6.3 fail to install Debian
body: <p>I'm having trouble installing gcc 4.6.3 on Debian squeeze. 4.4 is currently installed but I need 4.6.x to run php-hiphop. I've tried looking for similar problems but haven't found any with the error I have.</p>
  
  <p>I install using these instructions:</p>
  
  <pre><code>wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.6.3/gcc-4.6.3.tar.gz
  tar -xzvf gcc-4.6.3.tar.gz
  cd gcc-4.6.3
  ./contrib/download_prerequisites
  cd ..
  mkdir objdir
  cd objdir
  £PWD/../gcc-4.6.3/configure --prefix=/opt/gcc-4.6.3
  make
  make install
  </code></pre>
  
  <p>on the <code>make</code> command everything seems to be going fine for a good 20 or more minutes then, BLAMO! This pops up:</p>

  <p>I see what's causing it, stubs.h cannot be found, but how do I fix this? Is there a separate library I need, or has something else gone wrong? Thanks in advance.</p>
  
  <p><strong>EDIT</strong> downloading the multilib dependencies sorted out the above error. The make command ran for a good 5 hours, yes 5 hours, or so and then came crashing down with another error to do with zips and jars and I'm stumped.</p>
