Nice. I like go and looked at it a few times over these last few years. Did
you know that Google has worked on Go/R integration?  Christoph Best talked
about it at useR! 2015. No code release yet, and it depends on RPC and new

Let's the view of package author's of their own package an invariant :)  Most
are pretty impressed.

You "just" make that
  a) a SystemRequirements: entry and possibly add a line to say which
     Debian/Ubuntu and/or Fedora/Yum packages need to be installed
  b) possibly test for it in configure

Yes. Many other packages on CRAN depend on / work with external packages,
libraries or tools.

We'll help.  Let's work on this.
