PL/SQL :: Lock On Package

I am unable to compile my package because of a lock being held on it . Let me provide the details for better clarity .

select * from dba_ddl_locks where session_id=111 and owner='RAHUL';

session_id  owner       name                type                           mode_held         mode_requested
111           RAHUL     RAHUL_PKG        BODY                          NULL              None
111           RAHUL     RAHUL_PKG     Table/Procedure/Type      NULL              NoneThe session details of the session id 111 is as below

select sid,serial#,user#,username,command,status,process,sql_exec_start from v$session where sid=122

sid          serial#          user#                   username                     command                             status                     process      SQL_EXEC_START
111          3558             222                         RAHUL                      47                                   KILLED                   4420            13-DEC-12 02.00.00 AM

The strange this is that we have tried killing this session and the status above even shows ' 'KILLED', stilll the dba_ddl_locks is showing the lock details on the package RAHUL_PKG and we are unable to compile the package (the locking session is running since 13-Dec-2012 ) and we are unable to kill that . Also , is it like if i have executed a package that is referencing some other package then we wont be able to compile the referenced package until and unless the dependent package has completed its execution ??
