[R-pkg-devel] Tcl/Tk version difficulty building loon package on Unix ??

[Duncan Murdoch]

I've had some private messages with Wayne; here's some info and a 
question in case someone else wants to follow this up:

  - I can install his new version of loon on Ubuntu without a problem, 
but my R build uses tcl/tk 8.6.
  - I haven't built tcl/tk 9.0.1, and like Wayne, would like to avoid 
that.  Is there a Github action that would install it?
