Problem with tcl/tk and Rcmdr - urgent help required

Dear Ben,

It seems clear that the problem is in loading the tcltk package. To  
confirm
that, does library(tcltk) fail?

I'm not very knowledgeable about Mac OS X. I do have a MacBook,  
with OS X
10.5, however, and encountered no problems installing and running  
the Rcmdr
package. Have you seen the R Commander installation instructions  
for Mac OS
X 10.4, at
<http://socserv.mcmaster.ca/jfox/Misc/Rcmdr/installation- 
notes.html>? If
not, maybe something there will help.

I'm copying this response to Rob Goedman <goedman a mac.com>, who has  
provided
help before.

Regards,
 John

Hello everyone,

i have been searching the whole day, trying ANY solution offered  
by the
internet and before headbanging against the wall would like to try  
asking
for your help.

As many others, i am haveing problems loading the Rcmdr package with

Macbook

running Tiger 10.4.11. X11 version updated to the last one after  
having
manually installed.

I have also installed (obviously) the Rcmdr package with all  
dependencies.

However (damn) i keep having the following answer to the library  
(rcmdr)
command:

library (Rcmdr)

Carico il pacchetto richiesto: tcltk
Loading Tcl/Tk interface ... Error in dyn.load(file, DLLpath =  
DLLpath,

...)

:
  impossibile caricare libreria condivisa

'/Library/Frameworks/R.framework/Versions/2.8/Resources/library/ 
tcltk/libs/i
3

86/tcltk.so':

dlopen(/Library/Frameworks/R.framework/Versions/2.8/Resources/ 
library/tcltk/
l

ibs/i386/tcltk.so,
10): Library not loaded: /usr/local/lib/libtcl8.5.dylib
  Referenced from:

tcltk/libs/i3
8

6/tcltk.so
  Reason: image not found
Error : .onLoad non riuscito in 'loadNamespace' per tcltk
Errore: pacchetto 'tcltk' non caricato

The language is in italian but it basically says it cannot load  
shared
library.

x11 is running, the file tcltk.so phisically exists (i have checked

myself)

and both R and X11 are in their last updated version.

I have also tried restarting after updating X11. Can someone try  
to help

me?

i have recently swithced to mac and am having an important exam soon.

Thanks to anyone.

Ben
