I have installed the mechanize gem which uses webrobots and everything works fine on OSX (Snow Leopard). However, running "bundle install" on CentOS generates this error:

Invalid gemspec in [/home/account/public_html/rentwb/releases/20110708173025/vendor/bundle/ruby/1.8/specifications/webrobots-0.0.10.gemspec]: invalid date format in specification: "2011-07-01 00:00:00.000000000Z"
** [out ::] /usr/local/lib/ruby/site_ruby/1.8/rubygems/specification.rb:277:in _resort!': undefined methodname' for nil:NilClass (NoMethodError)

Any suggestions on a fix?

    I solved my own problem by adding the following to my Gemfile:

    gem 'nokogi'
    gem "webrobots", "~> 0.0.10", :git => 'git://'

    I'm not sure if it matters, but I added these lines above "gem 'mechanize'", in case bundler needs them to be specified beforehand.

    I hope this helps anyone else that runs into this issue.

    Also you could change "2011-07-01 00:00:00.000000000Z" to "2011-07-01" in the gemspec, until you update anyway...

    I would just use a standard date entry like 07-29-2011 or just change it to when generating the gemspec.
