I don't see how GDL2 could avoid garbage colection or similar mechanism.
 See http://www.gnustep.org/resources/documentation/gdl_2.html 
     (Resolving cycles within your model. A garbage collector)

Yes, it compile well on my computer. But with a previous version installed 
(I haven't tried from scratch).

Concerning GC, I don't think so: there's part where GC is needed 
(see above) and parts where retain/release or GC could be used.
