[Rd] FW: R-devel error

[Göran Broström]

Interesting, yesterday I had exactly this problem, but today I solved it 
(see the R-pkg-devel list) by _installing_ R-devel and

 > update.packages(checkBuilt = TRUE)

I also tried it on Martin's Fedora 26 example below. Worked fine (had to 
install some packages...)

On ubuntu 16.04.

Today I installed the latest versions of Rtools, MikTex and R-devel and still got the same error. We have also replicated this on another machine. I am able to successfully build the package in this way with R 3.4.3.
