R help - Apr 2013 - RJSONIO Installation

Trying to install rjsonio and I've run into a couple of issues.
1. When installing from R, it's starts to download, then I get
* installing *source* package 'RJSONIO' ...
ERROR: configuration failed for package 'RJSONIO'
* removing 'C:/Program Files/R/R-3.0.0/library/RJSONIO'

2. I've tried similar steps on the cmd(I'm win7).
I receive the same message, starts to install then, configuration failed.

3. Looking into the 'read_me' doc that comes with rjsonio it mentions
libjson C libraries.
They give a special command if you don't have this installed, which I tried,
but it didn't work.

At this point I want to generate the libjson libraries to try the other
'read_me' suggestions or just get it to work from R.
FYI, on the R CMD I've tried --binary and I've tried --build, neither
work.
Please help, running out of options.

R CMD build
will only work on Windows if you have Rtools installed. Visit your local CRAN
mirror and read... this is not exactly trivial.
