[SL] upgrade from 2.6.18 to 2.8.17

[Cliff B. <cli...@gm...>]

Hello, I'm trying to upgrade from sql-ledger 2.6.18 to 2.8.17, and
from postgresql version 8.0.8 -> 8.3.3

When I try try to upgrade through admin.pl, I get:Internal Server Error

In the apache logs, I see: Compilation failed in require at
/usr/local/sql-ledger-new/admin.pl line 85. [Sat Aug 16 17:32:45 2008]
[error] [client 192.168.1.109] Premature end of script headers:
admin.pl, referer: http://happy/sql-ledger-new/admin.pl

If I try to upgrade through log-in, I see the following:
∘ Upgrading to Version 2.8.17 ...
∘ Error!
∘ drop trigger del_vendor on vendor
∘ ERROR: trigger "del_vendor" for table "vendor" does not exist

Any suggestions as to how I can pull this off?  Do I need to take a
few intermediate steps?

Thanks,
Cliff
