Puppet

I tried to use Puppet and Facter (master version) with Ruby 1.9.1 on CentOS 5.2 and I succeed to make Facter work but I still have some errors :

# facter

#

#
Could not retrieve netmask_eth0: undefined method `each' for #

… and then it goes ok.

but puppetmasterd doesn’t work and the errors are :
