Please give more details: 

After having copying things into /usr/lib/gambas2 and run gbi2 (as root I 
imagine), what do you mean by "reload Gambas and test" ?

What do you mean by "I do/do not get the component loaded" ?

There is a design bug in the IDE at the moment: it caches all component 
information, and the cache is never flushed. So if a component is modified in 
the background, the component information is not refreshed, and so you do not 
see any new symbol or controls defined in the new component. You have to 
close the IDE and open it again.

Another point: you can debug your component without having to install it: just 
create a startup form or module in it, and use it for debugging.
