Looks like the test script expects to find the Cwd shared lib, but that file doesn't exist with pre-5.8 perls. There's 3 similar failures for 0.84 reported at http://cpantesters.perl.org/show/Module-ScanDeps.html#Module-ScanDeps-0.84.

One of those failures relates to perl 5.8.1 (where, presumably, Cwd.so does exist). However, for that particular perl, $Config::Config{dlext} is set to "bundle", so I'm speculating that the problem there is that Cwd.bundle doesn't exist. (But that's Darwin - and I don't know anything about the bizarre things that Darwin does.)

What does your perl -V produce ?

Cheers,
