[R-SIG-Mac] Problems with package gmp

[Terry A. Cox]

I have just upgraded OS X from Panther to Tiger 10.4.7, and R from  
2.2.1 to 2.3.1. I installed several packages (at system level), but  
gmp will not load:

 > library(gmp)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
	unable to load shared library '/Library/Frameworks/R.framework/ 
Versions/2.3/Resources/library/gmp/libs/ppc/gmp.so':
   dlopen(/Library/Frameworks/R.framework/Versions/2.3/Resources/ 
library/gmp/libs/ppc/gmp.so, 6): Symbol not found: ___gmpz_import
   Referenced from: /Library/Frameworks/R.framework/Versions/2.3/ 
Resources/library/gmp/libs/ppc/gmp.so
   Expected in: flat namespace
Error in library(gmp) : .First.lib failed for 'gmp'

gmp.so is present in the specified location, and gmp ran fine under  
my previous setup.

I would greatly appreciate some help.
