You could try (as superuser) "chmod 755 /usr/bin/python". If that doesn't work, you could try re-installing the python rpm. But if that doesn't work, there are so many things that depend on python that it might be simpler to re-install fedora. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
