The only way I can make the tests fail in this manner are to attempt to run the tests when the current working directory is not the directory of the extracted tarball.

$ pwd
/home/chris
[canker:]$ perl foo.pl

+tract.t .. 
ok 1 - use Archive::Extract;

foo.pl is just a path amended version of Khen1950fx's script.

That said, this is different to your original output which appeared to be from being in the perl source tree. Okay, let's have a go at breaking that.

bingos@harlequin:~/repos/perl.git$ cd t/
bingos@harlequin:~/repos/perl.git/t$ ./perl harness ../cpan/Archive-Ex
+tract/t/01_Archive-Extract.t 
../cpan/Archive-Extract/t/01_Archive-Extract.t .. ok

I don't know then. The tests in your output appear to be failing before they reach the 'archive' tests, namely because they aren't being run from the correct current working directory.
