title: Installing PIL on OS X Snow Leopard w/Xcode4 (no PPC support)
body: <p>Xcode4 dropped PPC support, so when I try building PIL, it throws hate:</p>

  <p>I ran that first line, manually, and removed the <code>-arch ppc</code> option and it didn't report back with any errors, but rerunning the build process ignores this manual attempt. `gcc-4.0 also does not exist, I symlinked it to gcc-4.2.</p>
  
  <p>I could go ahead and install Xcode3 and then 4, but I want to muck up my fresh install.</p>
  
  <p>Is there anyway to tell PIL to not compile for PPC? I did a grep across the distribution but i did not find a single mention of <code>PPC</code>. Any ideas?</p>
