source" anyway?

So, perhaps I'm showing some ignorance here. Do these guidelines allow for packaging pre-built gems (similar to pre-built java .jar files) or are they genuinely being built completely from source?

Maybe I'm confusing that with gems being built and generated in one step, rather than the rpm notion of extracting source/patching (%prep), building stuff (%build), and installing into buildroot (%install).

Ok, I'll give you 3 examples:

= Old guidelines, used from the time RubyGems were packaged for Fedora =

%prep

%build

%install
mkdir -p %{buildroot}%{gem_dir}
gem install --local --install-dir %{buildroot}%{gem_dir} \
            --force %{SOURCE0}




= What we are proposing =

%prep
%setup -q -c -T
mkdir -p .%{gem_dir}
gem install --local --install-dir .%{gem_dir} \
            --force %{SOURCE0}

%build

%install
mkdir -p %{buildroot}%{gem_dir}
cp -a .%{gem_dir}/* \
        %{buildroot}%{gem_dir}/




= What FPC is proposing =

%prep
%setup -q -c -T
pushd ..
gem unpack %{SOURCE0}

pushd %{gem_name}-%{version}
gem spec %{SOURCE0} -l --ruby > %{gem_name}.gemspec

gem build %{gem_name}.gemspec
popd
popd

%build
mkdir -p ./%{gem_dir}
gem install --local --install-dir ./%{gem_dir} \
    --force    ../%{gem_name}-%{version}/%{gem_name}-%{version}.gem

%install
mkdir -p %{buildroot}%{gem_dir}
cp -a .%{gem_dir}/* \
        %{buildroot}%{gem_dir}/


All three versions provide the same output, unless I did some mistake, since I did not tested it (actually the middle one was taken directly from rubygem-POpen4.spec). So which version you prefer? Please note that the "gem install" will always "unpack" the gem with some additional, for our case unimportant, steps. We do not distribute the .gem file anywhere.
