Changing the list of URLs:
Start the CPAN shell and issue
o conf urllist
...to see the urllist. Say you have one source and you want to replace it with another:
o conf urllist pop
o conf urllist push http://ftp.du.se/CPAN
o conf commit
reload index
update: JTOBEY seems to have taken over development of Date::Simple, however KASEI's module (1.03) is still on CPAN. Issuing an "install JTOBEY/Date-Simple-2.04.tar.gz" seems to work. However, that will get you a specific version and not the latest...
