I guess with "is not depend from", you mean "does not depend on"?

Logically, you are right. 'gb.gui' without 'gb.gtk' OR 'gb.qt4' is not 
really useful.

But actually, you can run then 'gb.gui' component without nothing else. 
You would get a Gambas error, but not an error of the dynamic loader.

Remember that the main point of having all these packages is preventing 
the user from installing something he doesn't need: forcing to install 
'gb.gtk' or 'gt.qt4' just because you need the Gambas runtime would 
carry megabytes of shared libraries!

Actually 'gb.form' can work without 'gb.form.stock', as soon as you 
don't use the standard built-in icon theme that is located in the 
gb.form.stock component.

Same logic: actually 'gb.desktop' can run without 'gb.desktop.gnome'. 
'gb.desktop.gnome' relies on a gnome desktop component that may carry 
most part of the Gnome installation if you have a dependency, even if 
you don't use it.

I don't know if you can make an optional dependency that would install 
only if a specific desktop is in use, and if it is possible in all 
distributions... If you can, just tell me. Otherwise, you must not 
create a dependency.

You should really, otherwise you will force people to install libraries 
they don't really need (imagine you need gambas on an embedded system 
without gui, i.e. you just need the runtime. You don't want all the GUI 
stuff).
