Here is my own version of the above:

ra88it:~ jcotton$ uname -a
Darwin ra88it.local 7.4.0 Darwin Kernel Version 7.4.0: Wed May 12 16:58:24 PDT 2004; root:xnu/

ra88it:~ jcotton$ /usr/local/bin/ruby -rdebug -e '$foo="x";bar="y";1000.times {|i| puts i }'
Debug.rb
Emacs support available.

-e:1:
(rdb:1) $foo
nil
(rdb:1) s
-e:1:
(rdb:1) $foo
"x"
(rdb:1) v foo
-e:1:(eval):1undefined local variable or method `foo' for main:Object
(rdb:1) v g foo
(eval):1: warning: parenthesize argument(s) for future version
-e:1:(eval):1undefined local variable or method `foo' for main:Object

-e:1:(eval):1undefined method `v' for main:Object
(rdb:1) step
-e:1:

"y"
(rdb:1) v bar
-e:1:(eval):1undefined method `v' for main:Object
(rdb:1) q
Really quit? (y/n) y
ra88it:~ jcotton$

Note: I have readline support built in to this version as well as the binary version that I installed in a 
different location this morning. The binary version does not have this debugger problem, however.

Thanks,
Jay
