<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto"><div>The message appears to be coming from forks.pm. Probably a warning added to perl 5.18.2 which is really really new (other versions don't care about this), and most developers would not consider 5.18 a fully stable release for production purposes (it will have lots of test features and messages that will get improved or dropped rather quickly). You can try updating the forks module from CPAN. Otherwise I would ignore it, as forks is sufficiently tested to know it works (it's not a MAKER module, it a widely used CPAN module - literally tens of thousands of scripts use it worldwide). The authors of forks.pm will take steps to silence the warning rather quickly, or the warning will be removed from the perl interpreter altogether.</div><div><br></div><div>Thanks,</div><div>Carson<br><br>Sent from my iPhone</div><div><br>On Apr 26, 2014, at 8:56 AM, Matthew MacManes <<a href="mailto:matthew.macmanes@unh.edu">matthew.macmanes@unh.edu</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">Hello, </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">
