2.10.3. Converting Subpackages

For any subpackages that define their name with the -n option, prefix their name with %{?scl_prefix}, as in the following example:
%package -n %{?scl_prefix}more
Prefixing applies not only to the %package macro, but also for %description and %files. For example:
%description -n %{?scl_prefix}rubygems
RubyGems is the Ruby standard for publishing and managing third party
libraries.
In case the subpackage requires the main package, make sure to also adjust the Requires tag in that subpackage so that the tag uses %{?scl_prefix}%{pkg_name}. For example:
Requires: %{?scl_prefix}%{pkg_name} = %{version}-%{release}
