What is the problem with the require?

If you said eval { use ... } I could understand why the eval "fails".

Hint: available_drivers() method after an import.

  eval "require DBI";
  unless ($@) {
   import DBI;
   print join(" ",DBI->available_drivers())."\n";
  } else {
   print "No DBI\n";

With two local perls...
