rubygems error message

[rounders]

i get the following warning message when using uniquify with rubygems 1.4.2 on a rails 2.3.12 project:

uniquify at /Users/fharbec/.rvm/gems/ruby-1.8.7-p334/bundler/gems/uniquify-0711699cc29c did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:
["Manifest"] are not files

This gem was intended to be used as an example in a RailsCasts episode. I'm not really maintaining it anymore, but if you want to submit a pull request to fix this problem let me know.
