[R] extracat , JGR, iWidgets install problems

[Michael Friendly]

[Environment: Win XP, R 2.10.1]

I'm trying to install the packages JGR and iWidgets required by the 
extracat package to make the interactive plots
in the package work.  I've tried various things, but nothing seems to 
work.  Here is my most recent attempt,
followed by my sessionInfo().

Does anyone have any suggestions how to make this work?

iWidgets requires 'JGR' in order to run correctly.
