Personally I wouldn't use Perl for this task unless it was something I knew I'd need to repeat over and over again. For a one-off comparison, I'd just use:

find -type f | sort > file-list.txt

... on each host to generate a lexically sorted list of files, and then compare the two lists using diff.
