[R-SIG-Mac] Errors loading gmp library

[Oscar Moreno]

I am getting errors loading gmp library.

System: PowerPC G5, DP 1.8 GHz, 1.5 GB memory
OS: Mac OS 10.4.7 (latest update from yesterday.)
R.Version output:

Error after library(gmp):

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

I am using R.gui from:
R-GUI-3266-2.3-Deployment.dmg
from http://r.research.att.com/

Pleas advise on what to do?  TIA
