I often make typing mistakes. The other day I upgraded to Perl 5.14. I decided to not use the old libraries of Perl 5.10.1 and Perl 5.12.3 which ./Configure suggested, since sometimes these don't work properly. So I had to reinstall all Perl modules. It turned out that I needed quite a few. My bad typing caused several problems. For example, I typed "cpanm CGI::Compress:Gzip" instead of Compress::Gzip and "cpanm Lingua::Stopwords" instead of StopWords.
