Configure ROOT adding “–enable-python --prefix=/Where/You/Want/To/Install/It --etcdir=/Where/You/Want/To/Install/It/etc/root” (if you do not set “etcdir”, it will default to “/etc/root”, regardless of what your “prefix” is).
Or … use my installation instructions (ROOT’s “etcdir” is automatically set to “${ROOTSYS}/etc”), adding just “–enable-python”: [url]Installing ROOT from Source
