rake gems:refresh_specs not working as expected...

Sorry should specify a little more info:

Rails 2.3.3, Ruby 1.8.6

Error trace:

Sure... I fixed this myself. I deleted the self-unpacked gem and rake gems:unpacked it.

But it had me slightly stumped and annoyed for a bit...

I wanted to unpack the gem so I could modify it, and didn't actually want any of the other gems unpacked.

I personally think the whole "specs" thing is a little nebulous... I can't find this mysterious 'specs list' which gets out of sync...

Why not just use the gemspec in the dir and compare against the desired version?

If you just want to unpack one gem, you can select it by passing the GEM= option to gems:unpack. The specifications are stored in each gem's directory, in a file called .specification - gemspecs would have been better, and making vendor/gems a real gem repo would have been even better. See #1128 Fix config.gem bugs and add more tests for some discussion on that issue...
