Hi Nick,

Thanks so much.  I had forgotten that this host had a bunch of updates recently, including jumping to perl 5.20 (but no rancid updates).  It looks like rancid3 is a bit of a jump (see initial commit message here: http://www.freshports.org/net-mgmt/rancid3/), so I’m trying the patch for now.  I’ll reply back tomorrow if this patch takes care of things so we’ve got something in the archives.
