One idea would be a shell one-liner pipeline using find, sort, xargs, 
stat, and/or cut, run once for each tree, put the output into text 
files, and then diff the text files.  Here's an StackExchange thread 
that discusses sorting in the face of filenames containing spaces:

Another option is Perl.  Here is a Perl script I wrote to compare mtime 
and size of files in two trees.  You could hack it up to check uid and 
gid for directories and files:
