Please create a symlink from /xfp to ~/f-prot/usr then it should work. Probably you are not running from Live CD and thus don't have root privileges, this is why klik wasn't able to do that for you. You need to do:
Code:
su
ln -s ~/f-prot/usr /xfp
Alternatively, you can add your user to the "sudoers" file.
