Package Passes R CMD check in Linux, Windows Binary Fails - r

Question

I submitted version 0.1-8 of a robust package I created to CRAN. R CMD Check passed on my computer runnning 64 bit Ubuntu and Rstudio. The Linux and Mac binaries are passing on CRAN. The windows binaries are failing on CRAN. The only difference between version 0.1-7 and 0.1-8 is I changed the namespace to adhere to the new version of R and I improved the documentation. None of the code has been changed.
https://cran.r-project.org/web/packages/robustreg/index.html
https://cran.r-project.org/web/checks/check_results_robustreg.html
Can anyone help me with the below error message?

According to its automatically-created GitHub mirror and the src/ directory there in, you do not have a file src/Makevars.win. And you now have a linking error with LAPACK routines.
Simply add a file such as this one added when you use RcppArmadillo.package.skeleton() containing just
PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
and you should be all set:
I am surprised this worked previously. You mostly got lucky--our documentation clearly says you need it.
