Create Index?

I've recently upgraded to version 6.4 which was compiled on RedHat Linux
ver 5.1
with no apparent problems.

and with a test table;

create table partref
    (partnum varchar(15) not null, desc varchar(15), vnum varchar(60));

then;

create index indpart on partref (partnum);

returns;

ERROR: partind: cannot extend


This worked fine w/version6.3 on the same system.

I looked around in the changes and re-checked the man page.
Am I missing something way to obvious??
