All of -n -x, -x and -c do the trick and take me to the Mojo/Home.pm line 25 error. I hadn't noticed that the error was precisely in that file: as soon as you pointed it out I remembered that the test t/mojo/home.t had failed before the (forced) installation. Thankfully, Google has something to say about it so I'll now concentrate on that.
(Please treat my english text just like Perl code, i.e. feel free to notify me of any syntax, grammar, style and/or spelling errors. Thank you!).
