I just installed ruby on Fedora 7, but I can’t bring up irb.

## Details

Using the Fedora7 Software Installer  
I installed ruby-libs-1.8.6-2.fc7.i386.rpm  
Then I installed ruby-1.8.6-2.fc7.i386.rpm  
As a result ruby now is in  
/usr/lib/ruby  
/usr/share/texmf/scripts/context/ruby  
/usr/bin/ruby  
/usr/share/man/man1/ruby.1.gz  
Also command such as  
ruby -v  
return  
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-linux]

BUT I can’t find irb. It doesn’t seem to exist. Commands such as find,  
locate and whereis can’t find it. I also tried other names such as  
irb18, irb186, irb1.8, irb1.8.6 and fxir and fxri.

If anyone has any advice, please let me know.

```
   Thanks,
