Can you please elaborate further why it's needed?  Couldn't be ruby-ffi
and/or ruby-sassc adjusted instead?

(I have hit that too when packaging wip/ruby-travis that IIRC has a
dependency that needs ruby-ffi... but why, e.g. python and/or py-cffi
doesn't need an interpreter that is marked PaX mprotect unsafe?)
