This usage of the `install` command in `Makefile` relies on the `-D` flag only available in the GNU implementation, so this fails by default on macOS: https://github.com/opensciencegrid/cvmfs-config-osg/blob/0e04406d604ea4d6e5b91347bdefcd769ac56c6b/Makefile#L15-L17 Is there a chance to update the calls to work with all implementations?
