you need to install gnat and glade. Do you normal development in
gnat, then a final (few?) compiles with glade, which distributes
everything according to the distribution file.

It really is painless. I had an assignment for first year students
which used it for a distributed chat/multiroom system. Couldn't
have been simpler.
