CPANdeps now links to the right bug-tracker
CPANdeps has for ages had links to each distribution's bug tracker. Trouble is, it always just linked to rt.cpan. Lots of people don't use that any more, preferring to, for example, use the one that github creates for each repository hosted there. META.yml (and META.json) have links to those.
Ben Bullock provided a patch to extract the info from the META files, and I applied it a few moments ago. There are quite a few different ways it can be specified, and in some places META.yml and META.json files have different data structures, so we may have missed a few. Please submit a bug report if you find any module whose bug tracker I'm not correctly linking to.
