Jruby shell script don't work on KSH shell

Could not use Jruby. Script shell is not really clean about params and other construction.
Here is an example:

$ jruby -v
/home/pouype/sandbox/jruby/bin/jruby[164]: java -Xmx378m -Xss1024k -classpath /home/pouype/sandbox/jruby/lib/bsf.jar:/home/pouype/sandbox/jruby/lib/jruby.jar -Djruby.base=/home/pouype/sandbox/jruby -Djruby=/home/pouype/sandbox/jruby -Djruby.lib=/home/pouype/sandbox/jruby/lib/ -Djruby=jruby -Djruby.shell=/bin/sh org.jruby.Main -v : not found

And if I put bash on ma station:
bash-3.2$ jruby -v
/home/pouype/sandbox/jruby/bin/jruby[164]: java -Xmx378m -Xss1024k -classpath /home/pouype/sandbox/jruby/lib/bsf.jar:/home/pouype/sandbox/jruby/lib/jruby.jar -Djruby.base=/home/pouype/sandbox/jruby -Djruby=/home/pouype/sandbox/jruby -Djruby.lib=/home/pouype/sandbox/jruby/lib/ -Djruby=jruby -Djruby.shell=/bin/sh org.jruby.Main -v : not found

It's the same.

I join a work about this Jruby Launch Shell Script.

Perhaps some part are alawys missing, but I think must of shell linked problem could be resolve with it.

(Still have a strange problem when I try testsutie about shell, but, dunno if it's some testsuite bugs or shell script bug. this patch work great for me, and for some test I have made... Hope it's ok for all)
