Hello,

I have installed ROR and when I try to create a project, i am getting a  
Exception, that don’t make me any sense.

I have installed it from gem, and ruby from apt Ubuntu repository. Do  
anyone have any idea? I have ever installed libfcgi, and nothing  
different.

Thanks,  
Breno Leitão

I’ve noticed some issue with Debian and Rails:  
Anyone interessed should look at  
[http://wiki.rubyonrails.com/rails/pages/RailsOnDebianUnstable](http://wiki.rubyonrails.com/rails/pages/RailsOnDebianUnstable)

Now i got a much better error message:

```
Rails requires Ruby version 1.8.2 (2004-12-25) or later.
You're running 1.8.2 (2004-12-23); please upgrade to continue.

```

Found the error.

The version of Ruby in Ubuntu Hoary was 2 days short of the final  
release.

Perhaps you should try upgrading to Breezy?
