Your Makefile.PL doesn't get that far. It gets as far as the "use DBI"
on line 15. You can't make any assumptions about what is installed
until *after* Makefile.PL has run.

You can put "i am a herring" in there for all the difference it will
make :-) Your Makefile.PL will still break at line 15. The solution
is rather involved:
eval "use DBI 1.21";
if($@) {
... stuff that uses CPAN.pm to install DBI goes here ...
}
eval "use DBI 1.21";
if($@) {
warn("
Something's badly broken with your environment, I couldn't
install DBI
");
exit(0);
}
Do that for every non-core module you want to use in Makefile.PL.
