You need to arrange for `(require <some-file-path>)' to load your
extension. See

 http://www.cs.utah.edu/plt/mailarch/plt-scheme-2002/msg01031.html

for information on how to make that work. 

IMPORTANT: `(require (lib "mzrl.so" "readline"))' in the message cited
above is supposed to be `(require (lib "mzrl.ss" "readline"))'.
