TCL脚本怎么调用STAF?

[loneba]

在winxp安装了STAF和TCL, 但是找不到STAF包。没看出来什么问题，哪位大侠帮忙看看？
% package require STAF
couldn't load library "C:/STAF/bin/TCLSTAF.dll": this library or a dependent lib
rary could not be found in library path

STAF安装在C盘，TCL安装在D盘
% set auto_path
C:/STAF/bin D:/Tcl/lib/tcl8.5 D:/Tcl/lib d:/tcl/lib/teapot/package/win32-ix86/li
b d:/tcl/lib/teapot/package/tcl/lib
% exit

C:\>set TCLLIBPATH
TCLLIBPATH="C:/STAF/bin"
