check_puppet.rb - Could not retrieve fact='concat_basedir'

[LorenzBischof]

calling facter like this: RUBYLIB=/var/lib/puppet/lib facter generates the following error:

Could not retrieve fact='concat_basedir', resolution='<anonymous>': no implicit conversion of nil into String

The environment is also not available as a fact. I can get the environment using puppet agent --configprint environment

I am using puppet 3.8.1

I don't use Puppet any more so it'll be a while before I get back to looking at this... if you can investigate I might be able to provide an update given more information for a workaround.
