Aah... my old arch enemy - the missing requiredAddons specification in the config.cpp ;D
Bap, have a look at this:
Suma's post on requiredAddonsBasically: you have to specify, in each addon, what other addons they depend on. Actually, I think you have to specify the whole dependency chain of addons. Example:
if A requires B and B requires C, then, in A:s config.cpp, one must have
requiredAddons[] = {B, C};
Greets!
