[R] JGR doesn't launch after updating to R 2.2.1

[Michael Kubovy]

Dear r-helpers,

After updating to R version 2.2.1, 2005-12-20, powerpc-apple- 
darwin7.9.0 (from binary), JGR wouldn't launch. I then deleted  
everything I could find related to JGR, and reinstalled it from the  
latest binary. Both R and JGR are installed in /Applications/ 
\~LocalApps/mathStat/.

Advice on how to identify the source of the problem?
