[R] Wayland backend for R

[Phillips Rogfield]

Dear Robert,

Thank you very much for your suggestion.

I solved by compiling R with --with-cairo, and installing cairo-devel 
and pango-devel.

Notably, you also need pango-devel.

The configure script does not complain if it is missing, but then 
plotting won't work.

Best regards.
