title: Is it possible to use MacPorts with ONLY Xcode 4.3 CLI tools installed?
body: <p>I understand that starting with Xcode 4.3 the CLI tools are a separate installation and that caused many issues with existing MacPorts installations upon upgrade.  This question is not about that problem.  With a brand new rMBP 15.4", I attempted to install <em>only</em> the CLI tools via download from the Apple Developer site.  Not only did MacPorts fail to find Xcode, but xcodebuilder itself failed to execute (simply hangs...).  I tried many iterations of using xcode-select to point to the CLI binaries, but I couldn't get either MacPorts or just the CLI binaries to work.  </p>
  
  <p>Is it simply not possible to only install (the wonderfully tidy and SSD-friendly) CLI tools and get MacPorts to work?  I was not able to find anybody that specifically confirmed or denied this in several searches here and on Google in general.  With a 128GB SSD, every GB counts... and the 4+GB Xcode install (99% of which I don't need) is a waste of space.  Is there something in the proper Xcode install that MacPorts requires? </p>
