I've just cd'd into my tk and tcl directories and done a 'cvs update', but
CVS didn't seem to do anything (it just said "Updating" on every directory
name).

I did "update to latest version" in Project Builder, and compiled TkLibrary
again, but still got the error:

ld: Undefined symbols:
_Tcl_MacOSXOpenBundleResources

I did 'clean active target' in Project Builder before compiling.

Hmmm... "rerun configure and rebuild"... is it possible to compile it
without using Project Builder now?  I remember reading a post from Jim that
said the UNIX makefiles hadn't been done.

No problem -- think we're getting there :)

That sounds good.  Don't work too hard, though :)

It always fails with my app.  And as it fails, I can't give the app focus
and so I can't interact with it.  A fairly major problem :(

Thanks for the reply.
