There's a file called ls-lR available on most CPAN mirrors, which lists every file on CPAN, but doesn't peek inside tarballs. So it lists Arff-Util-1.23.tar.gz. It's many megabytes in size though.
I've asked about this module in #toolchain on IRC for you, and miyagawa has spotted the reason Arff-Util is not in the module index. Arff-Util 1.24 was uploaded to CPAN, which pushed Arff-Util 1.23 out of the index. Arff-Util 1.24 was subsequently deleted.
