Thanks for the responses.  I should have been a bit more clear about my 
UNIX skills.  Not great, but I can move around and set permissions and 
look at things like environment variables.  So I had already set things 
to execute.  I still can't see what is up.  Here is the code(again) and 
files and symbolic links & path & permissions

Here is my beautiful code:

#!/usr/bin ruby

puts "Hello world!"

which produces these errors:

./test.rb: line 1: #!/usr/bin: No such file or directory
./test.rb: line 3: puts: command not found

/usr/bin is in PATH so it should not have a problem there:

/usr/lib/lightdm/lightdm:
/usr/local/sbin:
/usr/local/bin:/usr/sbin:
/usr/bin:/sbin:/bin:
/usr/games:
/usr/bin/ruby

ruby points, through symbolic links, to /usr/bin/ruby1.9.1

lrwxrwxrwx 1 root root   22 Jun 20 16:30 ruby -> /etc/alternatives/ruby

lrwxrwxrwx 1 root root 18 Jun 20 16:30 ruby -> /usr/bin/ruby1.9.1


-rwxr-xr-x 1 root root 5552 Mar 22 12:14 ruby1.9.1

And the code is here:

-rwxrwxrwx 1 john john 41 Jun 27 18:41 test.rb

I am going to /home/john to run the file ./test.rb

And everything is executable

#!/usr/bin/env ruby

or

#!/usr/bin/ruby

Prefer the former over the latter =]
