Hello team,

I installed jruby 1.6.1, as fully described below.
When I run the *jruby -v* command, it fails. Please see output at the end of
this post.

Downloaded file:
 *jruby-bin-1.6.1.tar*

When I verify Java on the Oracle site, I get the following:

        Your Java is Working
        Java update available

        Your Java configuration is as follows:

Vendor: *IBM Corporation* <http://java.com/>
Version: *Java SE 6*
Operating System: *Linux 2.6.32-71.24.1.el6.x86_64*
Architecture: *amd64*
*

*root@myserver # /opt/jruby* -ls -l

:/usr/local/bin:/usr/local/sbin:/suptools/bin:.:/opt/jruby/bin

When I try *jruby -v*, this is what I get:

 root@myserver  # jruby -v
JVMJ9VM007E Command-line option unrecognised: -client
Could not create the Java virtual machine.

Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-jar] [-options] jarfile [args...]
           (to execute a jar file)

where options include:
    -cp -classpath <directories and zip/jar files separated by :>
              set search path for application classes and resources
    -D<name>=<value>
              set a system property
    -verbose[:class|gc|jni]
              enable verbose output
    -version  print product version
    -showversion  print product version and continue
    -? -help  print this help message
    -X        print help on non-standard options
    -assert   print help on assert options

Any help will be appreciated!

Thank you
