hey guys,

can you spare some time?

i have this crazy thing with ruby.

when i enter irb and hit the return key, instead to run interactive  
ruby the shell gives me this :

radup@radup:~$ irb

Directory doc already exists, but it looks like it  
isn’t an RDoc directory. Because RDoc doesn’t want to risk  
destroying any of your existing files, you’ll need to  
specify a different output directory name (using the  
–op option).

any idea how to make irb work?

many thx,  
radu

This is a Ruby question, not a Rails question. You’ll want to ask on  
the Ruby list.
