What running program needs to have this environment variable set in its environment? Is it the shells that are created by Makefile rules when make dist is run? > Background: The COPYFILE_DISABLE=1 avoids having a second top-level > directory in your package when packaging on MacOSX.

This will create a Makefile variable, which is different to an environmental variable. That is, a line like "COPYFILE_DISABLE=1" will appear in the generated Makefile, and this will be substituted elsewhere in the Makefile if the COPYFILE_DISABLE variable is referred to. However there is nothing there to change environmental variables.
