That sounds reasonable. It turns out that the version of mzscheme that I got
is 4.2.4. Here is a transcript;

Welcome to MzScheme v4.2.4 [3m], Copyright (c) 2004-2010 PLT Scheme Inc.
> (list-ref(list 1 2) 3 4)
list-ref: expects 2 arguments, given 3: (1 2) 3 4

 === context ===
/usr/local/lib/plt/collects/scheme/private/misc.ss:74:7

Could it be that from 4.2.3 to 4.2.4 something changed in how mzscheme
reports such issues to the "outside world"? That might be a difference
between your and my own system. Another possible issue could be that there
is some interaction going on between the scheme that I build and the one
that my package manager got for me to use the .deb that I used to use?

Yours,
Kas.
