File::Spec version 3.4 required--this is only version 3.39_02 at Makefile.PL

[eserte]

Automatic build fails if a too old version of File::Spec is installed:

Output from '/opt/perl-5.16.3/bin/perl Makefile.PL':

File::Spec version 3.4 required--this is only version 3.39_02 at Makefile.PL line 4.
BEGIN failed--compilation aborted at Makefile.PL line 4.

In META.* only the following is specified:

configure_requires:
  ExtUtils::MakeMaker: '0'

However, Makefile.PL needs a higher version for ExtUtils::MakeMaker, and the File::Spec version is missing in META.*:

use ExtUtils::MakeMaker] 6.64;   # 6.64 for TEST_REQUIRES
use File::Spec 3.4;
