R help - Aug 2013 - Can not install rCharts

Hello again,

I was trying to install the rCharts package using following rule, however I
am getting error while doing that
> require(devtools)
Loading required package: devtools
WARNING: Rtools is required to build R packages, but no version of Rtools
compatible with R 3.0.1 was found. (Only the following incompatible
version(s) of Rtools were found:3.0,3.1)

Please download and install the appropriate version of Rtools from
http://cran.r-project.org/bin/windows/Rtools/ and then run
find_rtools().
> install_github('rCharts')
Installing github repo(s) rCharts/master from hadley
Installing rCharts.zip from
https://github.com/hadley/rCharts/archive/master.zip
Error: client error: (406) Not Acceptable


I am using R-3.0.1 with the latest Rtools, in my Windows machine.

Can someone help me out how I can resolve this error?

Thanks and regards,
