Is there a way we can get a better error message telling people they 
need to upgrade ninja?

Configure Output:

CMake Error at

(message):
   The C compiler "/usr/bin/cc" is not able to compile a simple test 
program.
   It fails with the following output:
  ....
   ninja: error: rules.ninja:18: unexpected variable 'deps'=
     deps = gcc
               ^ near here


Is there some simple test we can do to make sure ninja is the right version?
