Ruby 3.0 FTBFS issue (How to...?)

[Youhei SASAKI <uwabami@gfd-dennou.org>]

Dear folks, 

I'm currently working on a fix some FTBFS related to Ruby 3.0.

In the case of ruby-netcdf, ruby-lapack and ruby-fftw3, these packages
depend on ruby-narray, but ruby-narray in unstable is not built for Ruby
3.0.

So, I'm thinking of uploading ruby-narray to experimental first.
Is this the correct procedure? 

Best Wishes,
Youhei
