Comment (by pydave at gmail.com):

 Managed to get Jython running. There are some problems with the packages
 initial set up (the jython script is wrong). Otherwise you just have to
 change the jdk to one you actually have. (Although, installing 1.1 might
 have worked. Regardless, the lowest version I have is 1.3, so nuts to
 that.)

 What I did:
 {{{
 # install jython to get the build.xml file (this command will fail)
 sudo port install jython

 # Modify build.xml to use 1.4 instead of 1.1 (there's only one instance)
 sudo vim
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_jython/work/jython-2.1/build.xml
 +/1.1

 # change current jdk
 # I used script from here:
 http://www.macosxhints.com/article.php?story=20060121171126988
 # The following code should work, but is UNTESTED!
 cd /System/Library/Frameworks/JavaVM.framework/Versions/
 sudo ln -fhsv  1.4 CurrentJDK
 cd -

 # install again (this command should succeed)
 sudo port install jython
 }}}

 '''But''', Jython can't cache its packages.
 {{{
 $ jython
 *sys-package-mgr*: can't create package cache dir,
 '/opt/local/share/java/cachedir/packages'
 Jython 2.2a0 on java1.4.2_16 (JIT: null)
 >>> from java import *
 Traceback (innermost last):
   File "<console>", line 1, in ?
 ImportError: no module named java
 }}}

 So you have to change the cache dir:
 {{{
 # create a cache dir
 mkdir -p /tmp/jython/cachedir

 # tell jython where to go and to accept parameters (so we can run scripts
 like "jython app.py")
 # replace this line: CLASSPATH=/opt/local/share/java/jython.jar java
 org.python.util.jython
 # with this one: CLASSPATH=/opt/local/share/java/jython.jar java
 -Dpython.cachedir=/tmp/jython/cachedir org.python.util.jython $*
 sudo vim `which jython`
 }}}

 Now you should be able to run jython programs like this:
 {{{
 #! /usr/bin/env jython
 from java.lang import Integer
 print Integer(5).intValue()
 }}}


 So:
 Can the jython script (/opt/local/bin/jython) be updated?
 Can the build.xml file be set to use java 1.4?
 Can port be set to build with a specific version of java (instead of the
 user changing their symlink)?

 Thanks,
 -David
