[R-SIG-Mac] tcltk error

[Matthew Fero]

I know other have brought up tcltk issues in the past, but I hadn't  
encountered them until I installed the most recent version of R.app  
(with the R-2.5.0.dmg).  The issue arises when I try to load the  
Bioconductor "marray" package:

 > library(marray)
Loading required package: tkWidgets
Loading required package: widgetTools
Loading required package: tcltk
Loading Tcl/Tk interface ... Error in fun(...) : couldn't connect to  
display ":0"
Error : .onLoad failed in 'loadNamespace' for 'tcltk'
Error: package 'tcltk' could not be loaded

Curiously, the error does not occur in X11, and it also does not  
occur in R.app if X11 is running simultaneously.
