[R-pkg-devel] Failing vignette engine for package rasciidoc on solaris

[Andreas Dominik Cullmann]

Dear List,
one of my packages, rasciidoc (a simple wrapper to 'knitr' and 'asciidoc'),
includes a minimal vigentte engine.
When submitting the package with a vignette using that engine, the vignette is
re-built on all platforms except for r-patched-solaris-x86:
https://cran.r-project.org/web/checks/check_results_rasciidoc.html
https://www.r-project.org/nosvn/R.check/r-patched-solaris-x86/rasciidoc-00check.html

Maybe rasciidoc's vignette engine is somewhat superfluous, but since it works
for all platforms except solaris, I kind of would like to use it. 

I cannot reproduce the error using rhub:

And I happen to have no solaris box at hand for testing. 
Does anybody have any suggestion on how I could tackle this?
Thanks and best regards,
