Thanks Leo.  This came up in conjunction with a package (destiny) that used
nbconvertR as vignette engine.  We in bioc core have decided not to support
that
at this time and advised the author to move .ipynb content to inst/...,
take steps to inform
users of those resources, and introduce a .Rmd vignette so that destiny is
consistent
with general practice.

There are many .Rnw vignettes in Bioconductor so we can't "require" Rmd but
I think it is fair to say that Rmd is the de facto standard.

If there is a technical issue with macos and grid we should address that
separately.  I will try to have a look at this issue soon.  I hope others
will
look and advise even sooner. :)
