[WWdevel] database upgrade problem

[John J. <jj...@as...>]

Hi,

I am trying to get my development copy of webwork working.  In running 
wwdb_upgrade, I get the message

> Upgrading database from version 19 to 20...
> (Version 20 adds locations, location_addresses, set_locations and 
> set_locations_user tables to database, and add restrict_ip to set and 
> set_user.)

> isn't a string, the used length is longer than the key part or the

I don't know if this is a bug in the script, perhaps related to my 
version of mysql (4.0.20) (in which case I will be happy to file a bug 
report), or if it is caused by a problem on my end.  Any thoughts?
