[collectd] perl -mCollectd --error--> Bareword "LOG_ERR" not allowed while "strict subs" in use at Collectd.pm line 164.

[Trent W. Buck]

I was trying to load the OpenVZ.pm perl plugin into my collectd 4.8.2
instance on Ubuntu 10.04 LTS (Lucid).  It wasn't working; after some
digging I managed to produce the following issue.  It's still present
in git HEAD.  I can't see anyone else mentioning this issue in this
list's archives, so

  1. WTF is going on; and
  2. why is it (apparently) only affecting me?

Below is the transcript showing the issue on a Debian Sid which doesn't
have collectd installed yet, but just loading the pm directly from git.

PS: removing the "use strict;" line works around the problem, but I'd
prefer not to do that.
