I've just used perl -MCPAN -e shell to install DBI. Everything looked OK.

I then try to run this code:

use strict;
use warnings;
use DBI;
use Data::Dumper;

my @drivers = DBI->available_drivers();

print Dumper(@drivers);

foreach my $driver (@drivers) {  print "Driver: $driver\n";  my @data_
+sources = DBI->data_sources($driver);
  foreach my $data_source (@data_sources) {
    print "\tData Source is $data_source\n";
  }
  print "\n";
}

Which breaks as follows:

$VAR1 = 'ADO';
$VAR2 = 'ExampleP';
$VAR3 = 'Multiplex';
$VAR4 = 'Proxy';
$VAR5 = 'mysql';
Driver: ADO

Any ideas?
