WLST: script found "getopt" module on Windows, not on Unix

Question

I have a script that uses the "getopt" module. It works fine on Windows. It gets the getopt module from the wlst.jar, I assume. I copied the "wlst_v62" distribution and my script to Solaris and set it up to run, and it immediately fails, saying it can't find the "getopt" module.
I've stared at my classpath setting, verifying that the "wlst.jar" is in the classpath. I even trussed the java process, and I see it look in the "wlst.jar" for the getopt module, but it just doesn't find it.
What could I be doing wrong?

Answer 1

I wrote a short script called "syspath.py" that just prints the value of "sys.path". Curiously, the output seems close, but not quite correct. It shows the following:
sys.path[['.', '/var/tmp/Lib', 'home/u166705/work/wlst_v62/wlst.jar/Jython-Lib', 'home/u166705/work/wlst_v62/wlst.jar', '']]
Notice that the last two entries begin with "home/...", instead of "/home/...". That seems broken to me.
I'll include here my "syspath.py" script, and also my "wlst" bash wrapper.
--------wlst-----
#! /bin/bash
set -x
lp=
if [ "$1" != "-loadProperties" ]; then
scriptname="$1"
propsname="$(basename $scriptname .py).properties"
if [ -e $propsname ]; then
lp="-loadProperties $propsname"
fi
fi
java -classpath "$HOME/work/wlst_v62/wlst.jar:$HOME/work/wlst_v62/jython.jar:$BEA_HOME/weblogic/server/lib/weblogic.jar" weblogic.WLST $lp "$@"
--------wlst-----
--------syspath.py-------
import sys
#import getopt
print("sys.path[" + `sys.path` + "]")
exit()
--------syspath.py-------
Just in case, I printed the value of "$HOME" in my shell, and it's just "/home/u166705", as expected.
