I'm not sure why you're not just copying Text::Diff and Algorithm::Diff into your Perl script or distribution, but if you're interested in how the Longest Common Subsequence works, tye Dominus explained the short and the long of it in the documentation of Algorithm::Diff. If you're averse to using Algorithm::Diff then maybe Algorithm::Diff3 Text::Diff3 can be made to work for you.
