The fact that you have seen that one before gives me hope!

Today I downloaded the latest patched version of R-2.15.1 and built a
32 bit version of R from the source, mainly to A) make sure I could do
it again, and B) have a clean 32-bit version to work with.

In C:\R\R-2.15.1\library\RInside\examples\standard\Makefile.win I set
R_ARCH :=		--arch i386
and made no other changes. Then

make checkR -f makefile.win
yields
R is at C:/R/R-2.15.1

I copied the six dll's from C:\R\R-2.15.1\bin\i386 to
C:\R\R-2.15.1\library\RInside\examples\standard before running make
(just to be sure). Then

make -f makevars.win

ran without error, but

C:\R\R-2.15.1\library\RInside\examples\standard>rinside_sample0

gave the same  "Fatal error: unable to open the base package".

No one else has suggested any solution.

Thinking the error was probably thrown in Rcpp, I thought maybe I
should try building Rcpp from source, so I downloaded the latest
package and ran
R CMD INSTALL --build rcpp_0.9.13.tar.gz

but that did not eliminate the fatal error. I'm out of ideas.
