[plt-scheme] Problem with require statements using PLT4.x

I've just tried this under vista using 4.1 and I'm not seeing that
output. I'd guess that the XP/vista difference isn't significant and
that there is something else wrong. Possibly the planet cache got out
of sync somehow? Is this the first error you've seen? Do you get a
stack trace with the error message?
