Subject: rubygems: bad urls

I patched ruby gems successfully so that it outputs ruby packages so
that I can feed them into the Nix package manager system
(www.nixos.org).

One item of the generated output looks like this:

  jeremymcanally_pending_0_1 = rubyDerivation {
     name = "ruby-jeremymcanally-pending-0.1"; # full_name
     nameNoVersion = "jeremymcanally_pending";
     propagatedBuildInputs = [  ];
     src = fetchurl {
       url = "http://gems.rubyforge.org/gems/jeremymcanally-pending-0.1.gem";
       sha256 = "no hash";
     };
     meta = {
       homepage = "http://jeremymcanally.com";
       license = []; # one of ?
       description = "pending lets you define a block of test code that is currently \"pending\" functionality, similar to RSpec's pending method"; # cut to 120 chars
       longDescription = "pending lets you define a block of test code that is currently \"pending\" functionality, similar to RSpec's pending method.";
     };
  };


And you can see by "no hash" that something is wrong with this gem. It's
not only that one. By resolving dependencies for:

  up chronic rubygems-update xrefresh-server rb-inotify jeweler


these .gem urls are invalid:

  http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem
  http://gems.rubyforge.org/gems/jeremymcanally-pending-0.1.gem
  http://gems.rubyforge.org/gems/devver-construct-1.1.0.gem
  http://gems.rubyforge.org/gems/mhennemeyer-output_catcher-1.0.1.gem
  http://gems.rubyforge.org/gems/thoughtbot-shoulda-2.10.2.gem
  http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem
  http://gems.rubyforge.org/gems/jeremymcanally-pending-0.1.gem
  http://gems.rubyforge.org/gems/devver-construct-1.1.0.gem
  http://gems.rubyforge.org/gems/mhennemeyer-output_catcher-1.0.1.gem
  http://gems.rubyforge.org/gems/thoughtbot-shoulda-2.10.2.gem

So what's happening here?
Of course I can start fetching those gems manually from git repositories
etc. But isn't the purpose of gems that I can install them easily ?

Should I contact the authors and ask them to upload a new version?
Actually I have kind of bootstrapping problem: I'd like to use rake to
build the gem files. However rake requires jeweler. I can't install
jeweler because of bad hashs.

Is there a way to fix those gem urls?

Yes, I am new to ruby.
