I want o install ruby 2.0 and I have followed many tutorials, but none of them works, and the defaul repo `apt-get install ruby` brings me the 1.8 version (and due is debian has restrictions to update it if is not through the repo) any way to do it?

Ive tried this way

```
cd /usr/src
wget ftp://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p0.tar.gz
tar xjf ruby.xxx.tar.bz2
cd rubyxxx
./configure --enable-shared
make 
make install

```

and just that, I get error on the next steps, when I make a ruby -version I get this

```
-bash: /usr/bin/ruby: No such file or directory

```

the end of the tuto install

```
cd ext/openssl/
ruby extconf.rb
make install

cd ../readline/
ruby extconf.rb
make install

gem update --system

```

any idea how to do this in debian 6? thanks
