the 'use DBI;' already does a connect to the server and tries to read
the names of the available databases from the server:
I would check this assumption, because it strikes me as extremely
unlikely. DBI does not load any drivers at use or require/import time.
You could add some tracing statements of your own to confirm. See the
"trace_msg" method for example, which you could call directly after the
"use DBI" statement, to put something in your trace file.

This appears to be the result of a call to DBI->data_sources(). Are you
calling that somewhere?
