WARNING:  Invalid .gemspec format in '/Users/francois/.rvm/gems/ruby-1.9.2-p0@docendi/specifications/carmen-0.2.9.gemspec'

With or without Bundler, no differences.
Version 0.2.8 or 0.2.9 produce the same errors.

Any ideas ?

Thx a lot.

[budu]

One thing to note after reverting to version 0.2.8 using bundler and RVM, the warnings are still there as there's a gemspec copy in the specifications directory.

[fro]

I've removed the gemspec.

[burlesona]

Getting the exact same issue.

[jim]

Appears to be related to #79.

I've pushed out 0.2.10, which was built with Ruby 1.8.7. It's worth upgrading Rubygems itself if you can, but hopefully this helps those stuck on older versions. Please reopen this issue if the problem persists.

Thx Jim.
