That's my reading, yes.

I don't think you need to handle this at all. As you experimented, 
simply removing your otherwise empty configure script should suffice.

Note that by default (i.e., without --as-cran) the check is not 
included. The documentation for _R_CHECK_BASHISMS_ reads "... Default: 
false (but true for CRAN submission checks except on Windows).". Adding 
--as-cran effectively turns that check on.

Having said that, users can still run checks with --as-cran, but they 
would need to be aware that it requires certain infrastructure to run 
those checks. That's true for all packages though, not only yours, so I 
don't think you need to specially worry about it.

Cheers,

Rodrigo
