DateTime::TimeZone::Local uses File::Spec without use

[John Siracusa]

DateTime::TimeZone::Local (from CPAN) is missing:

    use File::Spec;

But later calls File::Spec->splitpath(...), resulting in the error:

Can't locate object method "splitpath" via package "File::Spec" at
/Library/Perl/DateTime/TimeZone/Local.pm line 44.
