Ruby-on-rails – bundler update fails with thesterious permission denied

I can't tell why bundler is looking for actionpack-1.4.0.gem, but it is causing my bundle update command to die.

Here are all the relevant transcripts (to the best of my knowledge…)

$ bundle update

OK, so it's failing due to a permission denied on this path, but there's no file there:

/mydev/ElectionManager(export-work)> ls /opt/local/lib/ruby/gems/1.8/cache/actionpack-1.4.0.gem
ls: /opt/local/lib/ruby/gems/1.8/cache/actionpack-1.4.0.gem: No such file or directory

Ok, let's look at the environment. Is there something fishy there?

/mydev/ElectionManager(export-work)> env

Nothing fishy. Let's look through all the code to see if actionpack-1 is ever even mentioned:

/mydev/ElectionManager(export-work)> grep  -r -i "actionpack-1" .
/mydev/ElectionManager(export-work)> 

Nope it's not mentioned. And what is in Gemfile?

$ cat Gemfile 


source :gemcutter

end

Ok that looks pretty good. What does gem think it knows about rails gems?
