Is there any way to change the character_sets_dir in mysql 4.1?

If I run a SHOW VARIABLES LIKE 'char%'; I get:

+--------------------------+-------------------------+
| Variable_name | Value |
+--------------------------+-------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/latin1 |
+--------------------------+-------------------------+

Can I change character_sets_dir to /usr/share/mysql/charsets?

Thanks,

Robert
