From my point of view this is a reasonable workaround for now.

All these tests where done using docker images from the rocker project,

Is this an error in the script or in R?

Dealing with .git folder when using R CMD INSTALL
Dear all,
quite a few package tools depend on R CMD INSTALL today for rapid testing
of a package, eg:
- devtools::install()
- BiocCheck::BiocCheck()
I've noticed that at least BiocCheck() doesn't ignore version control
folders like .git. Trying to find out why this was, lead me to R CMD
INSTALL.
I know this R CMD build ignores these files and folders by default, but R

I'm glad to hear that.
Then, I now do think this needs to be dealt with as a bug
(but I'm not delving into fixing it!)

I had alerted the owner of the server a few hours ago, but as
that is in California, it may need another few hours
before one of the R Core members can add an account for you on
R bugzilla.

to me this is not apparent. I just tried "R CMD INSTALL ." in a package
directory with a .git directory. This went without any problems. What do
you observe?

AFAIK a single-threaded OpenBLAS is used. When compiling R from source
on a CentOS system I have used the configure option
'--with-blas="-lopenblasp"' to link with the pthread version of OpenBLAS.
