This is due to Module::AutoInstall, which is generally considered
nowadays to have been a Bad Idea. Unfortunately, because of the way
Module::Install works there are likely to be modules using it on CPAN
for some time.
You need to set PERL_AUTOINSTALL=--defaultdeps in your environment. I
don't know if there's any way to put this in CPAN's config. You can also
set it to --alldeps instead to answer 'y' to all the questions (rather
than taking the default answer).
