Yes, there is no Atlas, and we had a small bug in as much as we depended on
atlas for all arches. That is fixed the most recent versions. Generally,
there are lots of successful builds:
http://buildd.debian.org/build.php?arch=arm&pkg=r-base
However, Peter D looked into this a little, and as I recall, found some FPU
isssues. You should probably get in contact with the Debian arm porters, as
well as r-devel. If you could act as a conduit between arm, R and Debian to
improve this, we would all appreciate this.
Regards, Dirk
