[plt-scheme] Typed Scheme and 3.99

Hi all,

What's the ETA for a version of Typed Scheme that works with 3.99?
I've just run into the following problem:

Welcome to MzScheme v3.99.0.2 [3m], Copyright (c) 2004-2007 PLT Scheme Inc.
> (require (planet "typed-scheme.ss"  ("plt" "typed-scheme.plt" 2)))
/home/pg/nhw/.plt-scheme/planet/300/3.99.0.2/cache/plt/typed-scheme.plt/2/2/private/rep-utils.ss:108:11:
lib: standard-module-name-resolver: collection not found: "big" in any
of: (#<path:/home/pg/nhw/collects> #<path:/home/pg/nhw/data/collects>
#<path:/home/pg/nhw/.plt-scheme/3.99.0.2/collects>
#<path:/bham/ums/linux/pd/packages/plt-scheme/lib/plt/collects>) in:
(lib "define-struct.ss" "big")

 === context ===
/bham/ums/linux/pd/packages/plt-scheme/lib/plt/collects/scheme/private/misc.ss:42:7


Some minor futzing didn't fix the problem.

Thanks,
Noel
