[plt-scheme] Trying to create executable fails

Hi all,

Latest svn fails while trying to create executable:
$ /usr/local/plt/plt-svn3111/bin/mzc --gui-exe mzrun mzrun.scm
mzc version 301.16, Copyright (c) 2004-2006 PLT Scheme Inc.
create-embedding-executable: can't find MrEd executable

 === context ===
/usr/local/plt/plt-svn3111/lib/plt/collects/compiler/embed-unit.ss:65:6:
find-exe
loop

Running mzc3m fails in the exact same way.
Does it need to be in the path? That's not a nice requirement, is it?
Still, that's probably not it, since I have a mzc3m in the path (but
it is the 'stable' 301***).

*** which unfortunately returns a segmentation fault when you try to
run a compiled program, but I think this bug has been solved already,
at least it doesn't show up anymore.
pmatos at euler ~/software/MzRun $ make
mzc3m --gui-exe mzrun mzrun.scm
