Maybe the testing error has something to do with CSPAN module File::Spec. It
has been installed from here:
http://search.cpan.org/~smueller/PathTools-3.40/lib/File/Spec.pm
http://search.cpan.org/~smueller/PathTools-3.40/lib/File/Spec.pm, following the
same process as other packages. Have attached a screenshot of all file-related
packages included in my Perl installation. I suppose File-Path is the package
containing File::Spec functionality. (On a side-note: searching for a package
named File-Spec returns no result.)
