R help - Nov 2009 - error when installing Rcmdr / tcltk on a Apple laptop

Hello,

I have installed R on my Apple Laptop. Next I wanted to install the  
package Rcmdr which requires the package tcltk. But then I get errors  
like:

The downloaded packages are in
	/var/folders/0p/0pD8fDrwHouNDsQ+k8dGmU+++TI/-Tmp-//RtmpSp4q7p/ 
downloaded_packages
Loading required package: tcltk
Loading Tcl/Tk interface ... Error in dyn.load(file, DLLpath =  
DLLpath, ...) :
   unable to load shared library '/Library/Frameworks/R.framework/ 
Resources/library/tcltk/libs/i386/tcltk.so':
   dlopen(/Library/Frameworks/R.framework/Resources/library/tcltk/libs/ 
i386/tcltk.so, 10): Library not loaded: /usr/local/lib/libtcl8.5.dylib
   Referenced from: /Library/Frameworks/R.framework/Resources/library/ 
tcltk/libs/i386/tcltk.so
   Reason: image not found
  etcetera

Can anyone give me a clue?

Thanks,

Karin Oudshoorn

It would be better to ask on R-sig-mac with full details as to bow you 
installed R.  But I expect you overlooked

http://cran.r-project.org/bin/macosx/tools/

and the tcltk .dmg.  You do need it if you just installed the 
'leopard' .pkg for 2.10.0 (earlier .dmg for R came with it).
