Обсуждение: No Database Drivers

I'm trying to get sql-ledger up and running.

(I sent some earlier email's but I can't tell if they were received because
I'm note receiving any posts from this list in my mailbox even though I am
subscribed.  I sent an email to the listmaster but it was returned.)

So I deleted /sql-ledger and ran setup.pl again:

Even though http://localhost/index.html.en works now,
http://localhost/sql-ledger/admin.pl now gives this error:

Error!
No Database Drivers available!

How do I correct this error?
Thanks,
Jerome
