It seems like Text::Levenshtein has been canonical in this field with repect to Perl. However, it may not be as well maintained as it could be. Jarkko Hietaniemi (co-author of Mastering Algorithms with Perl), in the POD for String::Approx (which is not appropriate for string comparisons) also mentions Text::WagnerFischer and Text::PhraseDistance. I don't find the latter still on CPAN. The Wagner-Fisher algorithm does look interesting but what I learn from Wikipedia leads me to believe it's just an implementation of measuring the Levenshtein distance. I have no idea whether it would be more or less suitable for your purposes than Text::Levenshtein, but might be worth a look to see if it fits your specific need. Sometimes where results are similar it just comes down to what fits better into your code design.
