It says:
tkn at tkn-laptop:~/src/scratch/scheme$ mzscheme -v
Welcome to MzScheme version 352, Copyright (c) 2004-2006 PLT Scheme Inc.

That should be the latest?

I'm, still getting the same error. My script looks like this:
tkn at tkn-laptop:~/src/scratch/scheme$ cat test.ss
#!/usr/bin/mzscheme -r
(require (lib "url.ss" "net"))
(require (prefix ssl: "ssl-url.scm"))
    (string->url "https://www.paypal.com:443"))))
tkn at tkn-laptop:~/src/scratch/scheme$ ./test.ss
ssl-url.scm:12:9: compile: unbound variable in module in: define-compound-unit

Bonus question; What's the difference between naming files *.ss and *.scm ?
