Taking this for a review.

Fixed few minorities (see changelog).
SPEC: http://bkabrda.fedorapeople.org/oauth-active-resource/rubygem-oauth-active-resource.spec
SRPM: bkabrda.fedorapeople.org/oauth-active-resource/rubygem-oauth-active-resource-0.4.7-2.fc15.src.rpm

* Please remove "testdir" macro
  - It seems it is not used anywhere

* Fix you name in ChangeLog
  - Please use your full name in ChangeLog

* Exclude the %{geminstdir}/doc from the package
  - It seems that this folder contains just the RDoc generated documentation.
    In this case, please exclude this folder, since we don't need to duplicate
    the documentation from generic RDoc location.

* The package doesn't work:

> require 'oauth_active_resource'
Gem::LoadError: Could not find activeresource (< 3.0.0) amongst [activemodel-3.0.10, activeresource-3.0.10, activesupport-3.0.10, builder-2.1.2, i18n-0.5.0, multipart-0.2.1, multipart-post-1.1.2, oauth-0.4.4, oauth-active-resource-0.4.7]

  - since the package .gemspec file defines dependency on activeresource 
    (< 3.0.0), but Fedora provides just version 3.0.10, the gemspec file should
    be patched accordingly (you can take a look at [1] how to achieve that).
  - However note that it is not clear if the gem can cooperate with
    activeresource 3.0.10 at all.

I'm currently trying to make it work, but at least one part of the functionality won't work because of changed signature of a method (see my comment on github [1]). It doesn't seem, that upstream is still maintaining, but I suggest waiting for a few days before we take another steps.

Closing this one as wontfix, because the package is unmaintained and doesn't work with Rails >= 3.
