Those are unusual.  Are you trying to tell it to build 32 bit?  If so,
you should use '-arch i386'.

Which line?

I haven't.  But I know the Tcl/Tk version included in 10.6 is newer than
in 10.5.

cd /System/Library/Frameworks/Tcl.framework/Versions

drwxr-xr-x  11 root  wheel  374  4 Sep 11:20 8.4
drwxr-xr-x  11 root  wheel  374  4 Sep 11:20 8.5
lrwxr-xr-x   1 root  wheel    3 14 Aug 10:00 Current -> 8.5

and on 10.5:

drwxr-xr-x  9 root  wheel  306 16 Sep 16:28 8.4
lrwxr-xr-x  1 root  wheel    3  6 Dec  2008 Current -> 8.4

Forgive my ignorance, I know next to nothing of Tcl/Tk... does
vtkTkRenderWidget only support Carbon and not Cocoa?  Why do you need to
build VTK using Carbon?

Anyway, perhaps you can try linking to the 8.4 version (on 10.6) and see
if that changes something.
