      ite_in   IN       VARCHAR2,
      ite2_in   IN       VARCHAR2,
      date_range_flag       IN       VARCHAR2,
      date_from             IN       VARCHAR2,

12:57:41 SQL> EXEC Pack1.get_Dset('MCE','MCE2','17/09/2013',
'22/11/2013',:te)
BEGIN Pack1.get_Dset('MCE','MCE2','17/09/2013','22/11/2013',
:te); END;

Unsure, which part of the suggestions do you fail to understand and not post the entire code. You still do not declare the procedure in your package specification.
See the below example,
SQL> ed
Wrote file afiedt.buf
  1  create or replace package test_pkg as
  2  procedure proc(p_in number, p_out out number);
  3* end test_pkg;
SQL> /
Package created.
SQL> ed
Wrote file afiedt.buf
  1  create or replace package body test_pkg as
  2  procedure proc(p_in number, p_out out number)
  3  is
  4  begin
  5    if (mod(p_in, 2) = 0) then
  6      p_out:=99;
  7    else
  8      p_out:=100;
  9    end if;
10  end;
11* end test_pkg;
SQL> /
Package body created.
SQL> variable num number;
SQL> exec test_pkg.proc(45, :num);
PL/SQL procedure successfully completed.
SQL> print num;
       NUM
       100
--This is what happens when you do not declare a procedure in Specification but attempt to call it.
--I have modified the specification only, leaving the body untouched, by changing name of procedure from proc to proc1 (which does --not exist in body. Any attempt to call it will result in error.

  1  create or replace package test_pkg as
  2  procedure proc1(p_in number, p_out out number);
  3* end test_pkg;
SQL> /

SQL> exec test_pkg.proc(45, :num);
BEGIN test_pkg.proc(45, :num); END;
