Fatal: build.log was created longer than 30 minutes ago.
As a standalone tool, it is important that you run cpanm-reporter
as soon as you finish cpanm, otherwise your system data may have
changed, from new libraries to a completely different perl binary.
Because of that, this app will *NOT* parse build.log files last modified
longer than 30 minutes before the moment it runs.
You can override this behaviour by touching the file or passing
a --force flag to cpanm-reporter, but please take good care to avoid
sending bogus reports.
