Have you looked at the R manual "Writing R Extensions" ?  

For every CRAN etc package, the step involves just

    R CMD INSTALL somePackage_0.1.2.tar.gz

so here, with the added flag, it was

    R CMD INSTALL --no-multiarch RInside_0.2.7.tar.gz

which results in a fresh local installation with a 64 bit static library
libRInside.a --- which is currently missing from the CRAN binary.

Hth, Dirk
