Stored procedures error PLS-00201

(p_username IN dba_role_privs.grantee%TYPE,
p_role OUT dba_role_privs.granted_role%TYPE) IS
v_username dba_role_privs.grantee%TYPE;
v_role dba_role_privs.granted_role%TYPE;
BEGIN
SELECT granted_role INTO v_role
FROM dba_role_privs
WHERE grantee = p_username
AND granted_role NOT LIKE 'CON%';
p_role:=v_role;
END;

This code will not compile I get error:

LINE/COL ERROR
