Why do they don't work?

[Vittorio De Martino]

I've just installed potato 2.2r2 and flooded this list with questions and 
problems.
Now, I'm trying to use "Gnome dialup utility" and it just doesn't work as I 
noticed many other  ppp programs under X.
Why does it happen? It's my fault or there's something wrong, uncomplete with 
the programs given in the official distro?
