> Binary ruby- and rubygem- packages ships .so files. These .so files 
> are picked up by RPM's automatic Requires/Provides generater and they 
> are listed among provides, e.g.:
>
> $ repoquery -q --provides rubygem-sqlite3
> rubygem(sqlite3) = 1.3.5-4.fc19
> rubygem-sqlite3 = 1.3.5-4.fc19
> rubygem-sqlite3(x86-64) = 1.3.5-4.fc19
> sqlite3_native.so()(64bit)

> However, these .so files are not useful outside of Ruby world and they 
> might even conflict with some system library (although I don't have 
> any example at my hand currently). So I believe, we should filter out 
> these automatic provides, as is done in Perl for example. Therefore, 
> since F19, there are available %{?ruby_default_filter} and 
> %{?rubygems_default_filter} macros, which allow to filter out these 
> provides.

> For your curiosity, this is their implementation:
>
> %ruby_default_filter %{expand: \
> %global __provides_exclude_from 
> %{?__provides_exclude_from:%{__provides_exclude_from}|}^(%{ruby_vendorarchdir}|%{ruby_sitearchdir})/.*\\\\.so$ 
> \
> }
>
> %rubygems_default_filter %{expand: \
> %global __provides_exclude_from 
> %{?__provides_exclude_from:%{__provides_exclude_from}|}^%{gem_extdir_mri}/.*\\\\.so$ 
> \
> }
>
> If nobody objects, I am going to propose usage of these macros into 
> Ruby packaging guidelines [1].
