Julian,
Thanks for work on this.
The bug report is essentially a duplication of #704805.

R sees the older version of its package and just does not use it. Not
"binary" in the classic sense.

Wrong assumption, sadly.
We also needed a rebuild at 2.10 which was not a major. For this, the patch
simply does not help at all. As that is a major shortcoming I don't think I
can use it.
