Good, glad you are up and running again.

I am wondering if we might want to make this an option to cmakexbuild? 
cmakexbuild -skip-lines="/Developer/usr/bin" which could be something 
you would put in your build command:

   SET (CTEST_BUILD_COMMAND cmakexbuild -skip-lines="/Developer/usr/bin")

Then, if you are seeing significant performance issues, you could add this.
