Followed Chandler’s advise and upgraded to the latest Xcode version last night (20-Sep)
which resulted in he following make issue:

make[2]: *** No rule to make target `/Users/eddyo/src/root-6.14.04/tutorials/dataframe/.df014_CSVDataSource.C.swp', needed by `tutorials/dataframe/.df014_CSVDataSource.C.swp'. Stop.

As usual , I forgot the “xcode-select --install”.

Problem solved ! Sorry for the noise

No, the original error message is actually caused by both CMake being “inherently broken” (it doesn’t re-run if a dependency is missing), and us being a bit casual in our definition of “the tutorials to be copied”:

When you configured ROOT for the first time, CMake saw tutorials/dataframe/.df014_CSVDataSource.C.swp in your source directory, and created a rule saying “copy that to the build directory, also do that whenever it changes”. Now that you have removed that file in the source directory, CMake is confused.

I have created https://sft.its.cern.ch/jira/browse/ROOT-9688
