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?
