Issue with puppet-lint 1.1.0 binary on lucid

[melissa]

When installing the puppet-lint 1.1.0 gem on lucid, I run into an undefined method error when running the binary against puppet code.

Since, in this instance, caller is a nil object, ruby doesn't know what to do when we call it in

if caller[0][/`.*'/][1..-2] == 'check'

on line 34. It looks like caller is a method provided by ruby (http://www.ruby-doc.org/core-1.8.7/Kernel.html#method-i-caller).

Testing it out, everything else seems to work fine

irb(main):002:0> require 'puppet-lint'
=> true

root@lucid:~# /var/lib/gems/1.8/gems/puppet-lint-1.1.0/bin/puppet-lint --version
puppet-lint 1.1.0

root@lucid:~# ruby --version
ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]

I'm not running into this issue on any other platform.

This has been fixed in master (I've been testing against a newer 1.8.7 patch number and it looks like the output of Kernel#caller changed between p249 and p358) and we be part of the next release.
