    If you use SuSE and you care a _lot_ about local security you must edit
    /etc/rc.config and set PERMISSION_SECURITY="paranoid". That way gnuplot
    would _not_ be suidroot. See the contents of /etc/permissions.paranoid:
    
    root@laser:/home/andrea# grep gnuplot /etc/permissions.paranoid
    # WHY ON HELL was gnuplot suid root !!!!!
    /usr/bin/gnuplot                       root.root        755
    
    Using PERMISSION_SECURITY="secure" was just installing tvscreen _not_
    suidroot.
    
    Using PERMISSION_SECURITY="easy" (and note: you are asked to set "easy"
    instead of "secure") is very riskious in a envinronment that has to be
    secured, but you asked for that so don't complain (e.g. about xtvscreen).
    
    I just tried once to fix the disinformation on the list about SuSE
    xtvscreen suidroot but Aleph One didn't accepted my email. I don't know
    why Aleph One didn't accepted my first email. Aleph?
