That is rude. This was discussed, and a fix layed out, within the last 24 hours.

Nonsense.  Look at the compile logs of /hundreds/ of r-cran-* packages across
/more than a dozen/ architectures.  They build.

Look eg at http://packages.qa.debian.org/r/r-cran-rms.html and click on build
log, or go to https://buildd.debian.org/status/package.php?p=r-cran-rms

Funny how it builds on all of our machines witout intervention, eh?
