That's basically what biocLite() does, so in this respect I do the same.

This was the key.  Second pair of eyeballs never hurt nobody, it seems!

Well, if you don't, I probably don't either.  So...
I squashed these and it worked like a charm.

THANK YOU!


just a side note:

Let us start with the obvious. You tell the linker about

tim at tim-ThinkPad-T420s:~$ ls -l /usr/lib64/R/library/Rcpp/lib/libRcpp.*
-rw-rw-r-- 1 tim tim 7523358 Oct 14 10:23
/usr/lib64/R/library/Rcpp/lib/libRcpp.a

/usr/lib64/R/library/Rcpp/lib/libRcpp.so

Previously the timestamp was June 24th, but otherwise no different.  That's
what threw me.  It turns out that I only needed the PKG_CPPFLAGS set for a
particular package (ExALT) that uses Rcpp in a fairly unusual fashion.  I
will keep those settings around but commented out so I remember this.

Anyways, it was the fault of PKG_CPPFLAGS, as you helped me deduce.

I am replying to the list just in case anyone has a similar problem in the
future.

Thanks again!  I really appreciate your work on Rcpp and support for it.

Best,
