[chef] OptionParser::MissingArgument ruby error chef 10.12

[Tim Dunphy < >]

Hello,

 I come from using puppet to manage our conf files and am very new to chef, but looking forward to diving in here since it seems like a great tool.

 I've just installed Chef 10.12 on centos 5.6 using a gem install. 

 /usr/bin/gem install chef ohai --no-rdoc --no-ri

When I go to run chef-solo for the first time I am running into a ruby error with the following output:

:~] #/usr/lib/ruby/gems/1.8/gems/chef-10.12.0/bin/chef-solo -c

/usr/lib/ruby/1.8/optparse.rb:451:in `parse': missing argument: -c (OptionParser::MissingArgument)

        from /usr/lib/ruby/gems/1.8/gems/chef-10.12.0/bin/chef-solo:25

 I tried doing a : gem install OptionParser

 But that hasn't changed the output.

I was just wondering if I might be missing a ruby module and/or what I would need to install to get chef running in this host for the first time. 

Thanks

Tim
