How to Grant ALTER command to Role

Hi,
I am trying to add ALTER SEQUENCE TO ROLE DEV_RL but I keep getting
this weird message.
--------------------------------------------
SQL> CREATE ROLE DEV_RL;

Role created.

SQL> GRANT ALTER SEQUENCE TO DEV_RL;
GRANT ALTER SEQUENCE TO DEV_RL
*
ERROR at line 1:
ORA-00990: missing or invalid privilege
----------------------------------------------

I am runing oracle 8i(8.1.6) and I have DBA role.

Any Idea !!!

Thanks,



SQL>

GRANT ALTER ANY SEQUENCE TO dev_rl;

Thanks alot..
