Some people have reported problems building ccl after updating to Xcode 5, or after updating to OS X Mavericks.
The version of Subversion that is included with Xcode 5 uses a new working copy format. Past versions of Subversion would upgrade working copies automatically and silently, but this time, the Subversion developers decided to require manual intervention.
Go to your ccl directory and run "svn update" by hand, and note that it prints out a message prompting you to run "svn upgrade". Run "svn upgrade" as it prompts.
On OS X Mavericks, it appears that installing Xcode does not install include files in /usr/include. It used to be the case that you could solve this problem by downloading the Command Line Tools from Xcode's preference panel. On Mavericks, this no longer appears to be an option. Instead, you must run "xcode-select --install" from a terminal. This will show a dialog, make you agree to some license or other, and then offer to download the files that ccl needs in order to build. It may even be the case that you don't need to download Xcode just to install the command-line tools, which would save you a 2 GB download if you only want to rebuild ccl. </blockqoute>
