[R] Some tcltk-related packages not loading (OS X)

[Michael Kubovy]

Dear r helpers,

In my exploration of the tcltk facilities of R I've had some success  
but some failures, and wonder if someone could point me to a  
solution. To begin:

******************************************************
 > sessionInfo()
Version 2.3.1 (2006-06-01)
powerpc-apple-darwin8.6.0

attached base packages:
[1] "tcltk"     "methods"   "stats"     "graphics"  "grDevices"  
"utils"     "datasets"  "base"

other attached packages:
igraph
"0.1.2"
******************************************************
A success:
******************************************************
 > library(tcltk)
 > tt <- tktoplevel()
 > tkpack(txt.w <- tktext(tt))
<Tcl>
 > tkinsert(txt.w, "0.0", "plot(1:10)")
<Tcl>
 >
 > eval.txt <- function()
+    eval(parse(text=tclvalue(tkget(txt.w, "0.0", "end"))))
 > tkpack(but.w <- tkbutton(tt,text="Submit", command=eval.txt))
<Tcl>
 >
 > tkdestroy(tt)
******************************************************
An interactive session ran successfully. One failure:
******************************************************
 > library(gtkDevice)
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/gtkDevice/libs/ppc/gtkDevice.so':

and another:

Error in library(tkrplot) : .First.lib failed for 'tkrplot'
******************************************************
I ran
 > installed.packages()
the two relevant lines are:
			Package	LibPath															Version	Priority	Bundle
gtkDevice	"gtkDevice"	"/Library/Frameworks/R.framework/Versions/2.3/ 
Resources/library"	"1.9-4"	NA		NA
tkrplot		"tkrplot"		"/Library/Frameworks/R.framework/Versions/2.3/ 
Resources/library"	"0.0-14"	NA		NA
******************************************************
I tried reinstalling gtkDevice from source, and got:
