MANY THANKS Willy for your help!!! :-)
Sorry for the incomplete informations!

Both at dolphin and konqueror double-clicking on it, brings up gdebi
package installer, that gave me the above error message.
Obviously, this was my fault according to its page: 
http://iplist.sourceforge.net/documentation.html

"Prerequisites

IPblock is part of the iplist package. iplist requires a 2.6.14 kernel 
or later with the option CONFIG_NETFILTER_XT_TARGET_NFQUEUE enabled 
(module or build-in). The download section lists the required packages 
on which iplist/IPblock depends on.
Installation
Install prerequisites (Ubuntu and Debian)
aptitude install prerequisites
Download the deb-package of iplist and install it (Ubuntu and Debian)
dpkg -i ./iplist*.deb"


So I tried again, and from konsole I gave:
1) sudo aptitude install prerequisites
that completed correctly, and
2) sudo dpkg -i ./iplist*.deb
that gave me the error messages that a) gksu, b) libnfnetlink0 and c) 
java 5-6 are not installed!
