Are you sure about that? I only have

Requires: ruby(abi) = 1.8

in my spec (which is for 1.1.1 though)

  

Source0: %{name}-%{version}.tgz
License: GPL
    

I think naming both licenses is correct here:

License: Ruby License/GPL

  

BuildPreReq: ruby >= 1.8.5, ruby-libs >= 1.8.5
    

Hmmm. Why PreReq?

I have BuildRequires: ruby, ruby-irb, ruby-rdoc in my spec.

Ruby Gems
    

RubyGems is the Ruby standard for publishing and managing third party
libraries.

Yours is a tad short :)

  

cd $RPM_BUILD_ROOT
rm -rf %{buildroot}
    

Hmmm. Either or, I think. Not both in one spec file :)

I also have a wad of rubygems which are packaged and should be published
somewhere (like a complete rails 2.1 environment, mod_passenger and other
stuff).

Cheers,
