Daniel,

sorry for the delay, I was away

yes, this is because the shared libraries Tcl8.3.shlb & Tk8.3.shlb 
are not found, if you include them in the same directory as Wish (or 
in a subdirectory referenced by 'alis' resource #1000 in Wish), Wish 
should work (but to have access to tcl packages like msgcat or http, 
you will need to include them in a subdirectory as well, and add that 
dir to your $auto_path).

you may want to look at the mac distribution of the Emu project 
http://sourceforge.net/projects/emu/ where I've used these techniques 
to be able to use several small wish executables with different 
embedded scripts all using a number of tcl packages & extensions 
included in a 'lib' subdir.

You may also want to take a look at my tclkit builds for macos 
classic (see previous message on the tcl-mac list).
tclkit solves all the tcl packaging problems in a much more elegant 
way using the new Tcl 8.4 vfs mechanism, but you can't use Tcl 8.3 of 
course... for an example see 
http://alphatcl.sourceforge.net/updates/mac-alphatcl-wiki.bin , this 
is the tclkit static binary with a small embedded script that uses 
package http to download & source an online wikit scripted document.

this is due to bgerror requiring package msgcat, which is not present 
in the resources. I think you've been given a workaround on c.l.t 
(include the contents of msgcat in the bgerror resource).

yes, the 'Simple' binaries are the statically linked ones, I agree 
that the names aren't very descriptive, the reason for the name 
choices is historical, probably Jim Ingham is the only one that knows 
why the executable are named so strangely... IIRC 
http://mini.net/tcl/825.html explains some of the naming conventions.

Hope this helps

Cheers,

Daniel
