Thanks for the quick response.

I just went to www.drscheme.org, Download, then chose:
   Platform: 'Windows 98 (and up) x86'
   Version: '204 (latest)'
Pressed the Download button, chose the German mirror, received the file 
'plt-204.exe' and used it to install PLT Scheme.

After all that, the program.ss file in my plt\collects\srfi\7 directory 
contains the lines:

(module program mzscheme
   (require (lib "0.ss" "srfi"))

I also did a CVS checkout to a different directory, the program.ss file 
there also contains those lines.

What am I doing wrong here?
