-    # 'fgrep: warning: fgrep is obsolescent; using grep -F'
-    # This occurs as output from fgrep which causes the ATLAS configuration 
-    # to get invalid return values, causing the configuration to fail

-    # If the version of grep is 3.8 or newer, we have to patch the ATLAS 
-    # source code to get rid of the warning produced by fgrep.
