[R-SIG-Mac] Tktable and BWidget on leopard

[shimpo]

I am trying to run R 2.6.1 on OS X 10.5 in order to use some programs
with R-tcl/tk, Tktable, and BWidget.
I installed Tktable and Bwidget in /usr/local/lib.
These can be loaded from "wish" as follows:

% package require BWidget
1.7
% package require Tktable
2.9

However, from R, only BWidget can loaded:

> tclRequire("BWidget")
<Tcl> 1.8 
> tclRequire("Tktable")
[1] FALSE
Warning message:
In tclRequire("Tktable") : Tcl package 'Tktable' not found

Did anyone have same problem and resolve this ?
