Dear Simon,

Please excuse my confusion, but I am pretty certain that Tcl/Tk is  
installed in Leopard by default (I certainly do not recall installing  
Tcl/Tk myself).  In fact, when I run ./configure in the source  
directory of R 2.8.1 branch the relevant lines of the output confirm  
this:

checking for tclConfig.sh... no
checking for tclConfig.sh in library (sub)directories... /usr/lib/ 
tclConfig.sh
checking for tkConfig.sh... no
checking for tkConfig.sh in library (sub)directories... /usr/lib/ 
tkConfig.sh
checking tcl.h usability... yes
checking tcl.h presence... yes
checking for tcl.h... yes
checking tk.h usability... yes
checking tk.h presence... yes
checking for tk.h... yes
checking whether compiling/linking Tcl/Tk code works... yes

and then again confirmed at the end:

R is now configured for i386-apple-darwin9.6.0

   Source directory:          .
   Installation directory:    /Library/Frameworks

   C compiler:                gcc-4.2 -std=gnu99  -g -O2
   Fortran 77 compiler:       gfortran  -g -O2

   C++ compiler:              g++  -g -O2
   Fortran 90/95 compiler:    gfortran -g -O2
   Obj-C compiler:	     gcc -g -O2

   Interfaces supported:      X11, aqua, tcltk
   External libraries:        readline
   Additional capabilities:   PNG, JPEG, iconv, MBCS, NLS, cairo
   Options enabled:           framework, shared BLAS, R profiling, Java

   Recommended packages:      yes

I can therefore only conclude that the 2.8.1 binaries for the package  
tcltk that I got by
Leopard builds can be installed as follows - paste in Terminal (for R  
2.8.x):

curl -s http://r.research.att.com/R-2.8-branch-leopard- 
universal.tar.gz | sudo tar fvxz - -C /

were compiled against Tcl/Tk library for X11. Why not compiling them  
against the Tcl/Tk framework already available in Leopard?

Best regards,

Ivan
