Mmmmh. Let's do it step by step, I may have missed something on your question.
You just want to *install* JPython, don't you (I mean not make a custom 
version of it)?

I just grabbed JPython11.class. Then 'java JPython11'. The installer is
launched and asks for a directory. I say '~/JPython-1.1'. Installs ok.

Then:

<dcalvelo at llorio ~/JPython-1.1> ls -F
ACKNOWLEDGMENTS  NEWS       docs/        jpython*     registry
LICENSE.txt      Tools/     html/        jpython.jar  rules/
Lib/             cachedir/  install.idb  jpythonc*    uninstall.class
Makefile         demo/      installer/   org/         util/

Notice the 'jpython.jar' and the 'jpython' exe. Indeed:

<dcalvelo at llorio ~/JPython-1.1> cat jpython
#!/bin/sh
# This file generated by JPython installer
# Created on Thu Sep 07 10:51:55 GMT+0:00 2000 by dcalvelo
exec /usr/bin/java -Dpython.home=/home/dcalvelo/JPython-1.1 \
-classpath "/home/dcalvelo/JPython-1.1/jpython.jar:$CLASSPATH" \
 org.python.util.jpython "$@"

You have the sources in org/python/core, but they have already been compiled.

<dcalvelo at llorio ~/JPython-1.1> ./jpython
JPython 1.1 on java1.0.6 (JIT: kaffe.jit)

Works like a charm. This is a Debian woody, but I had previous versions on
RedHat and Mandrake without any hassle.
