Archive::Tar version: 2.04
Perl version: v5.18.2 - built for darwin-thread-multi-2level (Mac OS 10.10)
If a tar contains a hardlink to another file within the tar and the path is too long, Archive::TAR will either truncate the filename or try to create a link to ././@LongHardLink
It seems that linux and mac versions of tar cvzf handle long hardlink names differently. I'm
seeing various errors. I've attached a script that reproduces the error. This is what I get
when I run it:
ERROR: Making hard link from '././@LongHardLink' to '/tmp/untar_dir/untar_bug/some/really/really/really/really/really/really/really/really/really/really/long/path/OneMoreSub/file.txt' failed at /Library/Perl/5.18/Archive/Tar.pm line 953.

But I've also seen errors like this:

The full filename should be:
untar_bug/gravity-dashboard/node_modules/jsdom/node_modules/contextify/build/Release/MoreLevel/contextify.node
