See below.

I just tried 301.12 from the above source. I put a symbolic link from 
/usr/local/bin/newmzscheme to the mzscheme in the bin directory of 
301.12 so I could use the same shell script. (Previously I had a 
symbolic link to 301.) When I run the shell script from Terminal, it says:

make-directory: cannot make directory: /Users/plragde/Library/PLT 
Scheme/planet/300/301.12 (Permission denied; errno=13)


  === context ===
/Applications/PLT Scheme v301.12/collects/planet/resolver.ss:172:2: resolver

Perms on ~/Library and all the way down are drwxr-xr-x, which look right 
to me. My shell script starts:

#!/bin/sh
#|
#exec /usr/local/bin/mzscheme -M errortrace -qgr "$0" "$@"
exec /usr/local/bin/newmzscheme -M errortrace -qgr "$0" "$@"
|#

before continuing with some simple Scheme stuff (requiring my module, 
and invoking a function that it exports). It's the module which requires 
WebIt! by way of PLaneT. All this should run as me, right?

Oh, and when I ran setup-plt last time to fix things, there were only a 
couple of obscure things in /collects that it compiled, plus WebIt!, 
which was the only thing in my PLaneT cache (I cannot type PLaneT 
without five tries at it...) --PR
