LISP and DCL

I have a autolisp program made for Bricscad windows version and I want to put it in Bricscad Linux. With the first it run OK but in linux (ubuntu 11.04) there are no conection between lisp file and dcl file.

This is the listp file:

(defun c:acercaetres (/ acercadeiddcl nosalir x y)
      (setq acercadeiddcl (load_dialog "~/etres/inicio/acerca.dcl"))
      (if (< acercade_id_dcl 0)
          (progn
             (alert "Archico ACERCA.DCL no encontrado")
             (exit)
          )
       )
      (setq nosalir t)
      (while nosalir
         (if (not (new_dialog "acercade_etres" acercade_id_dcl))
             (progn
                (alert "No se encontro el dialogo ACERCA DE en el archivo ACERCA.DCL")
                (exit)
             )
         )
         ;(setq x (dimx_tile "vista")
         ;      y (dimy_tile "vista")
        
         ;(start_image "vista")
         ;(fill_image 0 0 x y 160)
         ;(slide_image 0 -97 180 156 "~/etres/inicio/logo_etres.sld")
         ;(end_image)
         (action_tile "accept" "(done_dialog 10)")
         (setq accion (start_dialog))
         (cond ((= accion 10)
               (setq nosalir nil)
           )
         )         
      )
      (unload_dialog acercade_id_dcl)
      (princ)
)

And this is the dcl file:

acercadeetres: dialog
         {label="ACERCA DEL CONVERSOR DWG ---> LIDER V.1 © 2.008";
          :row
            {width=60;
            }
          :row
            {alignment=centered;
             fixed_width=true;
               :column
                 {:paragraph
                  {:text_part
                     {label="Esta aplicación ha sido desarrollada por:";
                     }
                   :text_part
                     {label=" ";
                     }
                   :text_part
                     {label="Manuel Romero";
                     }
                   :text_part
                     {label="Director de Proyectos";
                     }
                   :text_part
                     {label=" ";
                     }
                   :text_part
                     {label="ETRES Consultores";
                     }
                   :text_part
                     {label="Diseño de Edificios Energéticamente Eficientes";
                     }
                   :text_part
                     {label="www.etresconsultores.es   mromero@etresconsultores.es";
                     }
                  }
                 }
              }
       spacer_1;
       ok_only;
       }
