Can't get extproc listener working - help?

I'm trying to get intermedia configured on my Oracle 8i server, but can't get the external procedure mapping going. Can someone help?

tnsnames.ora:

LOCAL.PHILO =
  (DESCRIPTION =
(ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = cj49297-b)(PORT = 1521))     )
(CONNECT_DATA =

      (SID_NAME = ORCL)
    )
  )

EXTPROC_CONNECTION_DATA =
 (DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)

               (KEY = ORCL))
(CONNECT_DATA = (SID_NAME = ep_agt1)))

listener.ora:

LOCAL =
  (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = cj49297-b)(PORT = 1521))
  )

SID_LIST_LOCAL =

	(SID_LIST = 
		(SID_DESC = (SID_NAME = ep_agt1)
    	    (ORACLE_HOME = e:\oracle)
            (ENVS = LD_LIBRARY_PATH=e:\oracle\ora81\ctx\data)
            (PROGRAM = extproc)
         )
         (SID_DESC =
     		(GLOBAL_DBNAME = local.philo)
      		(ORACLE_HOME = E:\ORACLE)
      		(SID_NAME = ORCL)
    	 )
     )

Trying to run
exec ctx_output.start_log('log')

From SQLPlus gives me this error:
ORA-20000: interMedia Text error:
DRG-50704: Net8 listener is not running or cannot start external procedures

What am I missing?

TIA,
