"successfully installed DBI"

You already had DBI and the associated modules installed. We established this yesterday after much tortuous discussion. You've turned on tracing which has given you the same error and the same line number to look at as yesterday. Despite repeated advice you don't seem to have looked at the code Perl tells you is failing.

you don't seem to have looked at the code Perl tells you is failing.
Can you tell me which code I should check ?

If you read what you post, you already know where to look. We discussed this at length yesterday, you've ignored all the advice given. If you keep doing so you won't progress this issue.
