Comment # 4 on bug 1049973 from Marcus R�ckert

no they should not conflict:

if you wanted to go for a conflict based solution it would be:

%if "%{rb_default_ruby_suffix}" == "%{rb_soname}"
Provides: ruby-default = %{version}-%{release}
Conflicts: otherprovider(ruby-default)
%endif


In general we want to support installing multiple ruby versions in parallel.
The problem here is that ruby 2.2 was the default ruby and was deleted before
we could release a version that wasnt a default ruby.

what do you get from

zypper rm libruby2_2-2_2

something must be still requiring the old ruby.
