Sorry for the delay (we are in different time zones),
I know my first post was kinda short, I did not gave enough info.
The error happens when I try to run the project.

I created the project with the dependency using this command:
" dub init allegrotest derelict-allegro5"
no errors are shown, the project is created just fine.

Then when I run the command: "dub run ", dub returns the error 
"Could not find a valid dependency tree configuration: "

If I run the command: "dub run --bare" dub returns this error: 
"Root package allegrotest contains reference to invalid package 
derelict-allegro5 0.0.4"

derelict-allegro5 might be the culprit... but maybe not entirely.

Whenever I ran the command: "dub build -v" it returns:
"Using dub registry url 'http://code.dlang.org/'

it is definitely derelict-allegro5's fault.

this is my (auto-generated) dub.sdl file:
« name "allegrotest"
description "A minimal D application."
copyright "Copyright © 2016, pedro"
authors "pedro"
dependency "derelict-allegro5" version="0.0.4" »

My platform is a linux-lts Antergos (basically Arch).
