This tool recursively compares file names, mtimes, and sizes in two
directory trees, and reports any differences found:

http://search.cpan.org/~dpchrist/Dpchrist-Directory-1.018/perl-bin/dirdiff


Assuming you have a working Perl cpan installation, you can install the
Dpchrist::Directory module and dirdiff script as follows:

    cpan Dpchrist::Directory
