body: <p>I am trying to compile PJSIP2.1.0 for iOS on Mac 10.9.(Xcode 5.0). But I'm getting some errors  when I run <code>./configure-iphone</code>.</p>
  <p>Below are the errors,</p>
  <pre><code>configure-iphone: DEVPATH is not specified, using /Applications/XCode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer
  configure-iphone: IPHONESDK is not specified, choosing iPhoneOS7.0.sdk
  ls: /Applications/XCode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/gcc/arm-apple-darwin*: No such file or directory
  configure-iphone error: unable to find gcc for iPhoneOS7.0.sdk. If you think you have the right gcc, set the full path in CC environment variable.` 
  </code></pre>
  <p>Is anybody can help me? Thanks</p>
