Thx for the reply, and sorry for my ambigious question :)

I import like this:

import std.string;
import std.c.stdio;

import derelict.util.exception;
import derelict.opengl.gl;
import derelict.sdl.sdl;
import derelict.sdl.image;
import derelict.opengl.glu;

import structures;

And get this error:
structures.d(19): identifier 'GLubyte' is not defined
