R help - Aug 2007 - error message: image not found

I have a R version 2.4 and I installed R version 2.5(current version)  
on Mac OS X 10.4.10. I tried "dyn.load" to load a object code  
compiled from C source. I got the following error message:

Error in dyn.load(x, as.logical(local), as.logical(now)) :
	unable to load shared library '/Users/jusong/Desktop/BPM/R/group.so':
   dlopen(/Users/jusong/Desktop/BPM/R/group.so, 6): Library not  
loaded: /Library/Frameworks/R.framework/Versions/2.4/Resources/lib/ 
libR.dylib
   Referenced from: /Users/jusong/Desktop/BPM/R/group.so
   Reason: image not found


How can I fix this problem?
