Dear People

  I can't figure out how to fix this problem: rgl won't run under R  
2.14.2 (it was working for me before under 2.14.0). The error message  
is:

 > library(rgl)
Error : .onLoad failed in loadNamespace() for 'rgl', details:
   call: dyn.load(file, DLLpath = DLLpath, ...)
   error: unable to load shared object '/Library/Frameworks/ 
R.framework/Versions/2.14/Resources/library/rgl/libs/x86_64/aglrgl.so':
   dlopen(/Library/Frameworks/R.framework/Versions/2.14/Resources/ 
library/rgl/libs/x86_64/aglrgl.so, 6): Symbol not found:

   Referenced from: /Library/Frameworks/R.framework/Versions/2.14/ 
Resources/library/rgl/libs/x86_64/aglrgl.so
   Expected in: dynamic lookup

Error: package/namespace load failed for ‘rgl’

I tried re-installing the package several ways, including from R, both  
binary and type='source', and from Terminal using R CMD INSTALL  
rgl_0.92.858.tar.

I found some threads with this error but no solutions that I could  
understand.  I am an R user, not a developer.  Do you have any idea  
how to fix this?

Thanks for your help,

Mark
