If you want to provide options to the gem during compile process,
please place them after double dashes:

gem install rsruby -- --with-R-dir=

Also, a few recommendations:

* for --with-R-dir, supply the root directory of R installation, not
the bin directory
* Try to install R in a path without spaces, path with spaces are
always problematic. If you can install in a different folder, try
using Substituted drivers (subst):

subst X: "C:\Program Files\R\R-2.11.1"

gem intstall rsruby -- --with-R-dir=X:

* Ensure you have successfully installed a compiler (like DevKit for
RubyInstaller)

HTH,
