[BioC] Error loading tcltk for tkWidgets and widgetTools on duo Intel Mac under OS X

[John E. Cornell, Ph.D.]

Dear Bioconductor group:

I am running R 2.3.1 on a duo core Intel MacBook under OS X.  While all the
R and Bioconductor libraries appear to run ok, I got the following error
message when loading widgetTools.

> library(widgetTools)
Loading required package: tcltk
Loading Tcl/Tk interface ... 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/tcltk/libs/i
386/tcltk.so':
  
dlopen(/Library/Frameworks/R.framework/Versions/2.3/Resources/library/tcltk/
libs/i386/tcltk.so, 10): Library not loaded: /usr/X11R6/lib/libX11.6.dylib
  Referenced from: 
/Library/Frameworks/R.framework/Versions/2.3/Resources/library/tcltk/libs/i3

  Reason: image not found
Error: .onLoad failed in 'loadNamespace' for 'tcltk'
Error in fun(...) : Package tcltk not able to be loaded!
Error: .onLoad failed in 'loadNamespace' for 'widgetTools'
Error: package/namespace load failed for 'widgetTools'

Can anyone help me with this error.

Cheers,
