[Perl] spellchecking

[nothingmuch]

I am the maintainer of a large text file archive. Recently i've implemented 
a simple content search engine, which i would like to enhance by adding a 
spell checker. I've searched, and have not come up with an elegant 
solution, and i would just like to ask around before making my own 
approximate string matcher.

String::Approx will not work, as it needs to run on MacPerl, and that 
module contains some xs code which i cannot port.

Thanks in advance,
