Subject: Re: Ruby Debugger options: v[ar] g[lobal] ...

Tonight I fooled around with the debugger, and I found that the v[ar] g[lobal] and v[ar] l[ocal] 
commands work fine with my old version of Ruby that came with my machine (1.6.8), but they don't 
work with the newer version that I compiled myself: 1.8.1 [powerpc-darwin]. When I try to list 
variables with the debugger in version 1.8.1, I get the error message '1undefined local variable or 
method `g' for main:Object'.

Anybody have any idea what's wrong? I'm running Mac OS 10.3.
