In constant battle to install 
Ruby 1.9.2 on an RPM system (OS is based off of CentOS), I'm trying again with RVM.
So once I install it, I then try to use it:
[root@quackwall ~]# rvm use 1.9.2
Using /usr/local/rvm/gems/ruby-1.9.2-p136
[root@quackwall ~]# 
ruby
bash: ruby: command not found
[root@quackwall ~]# which 
ruby
/usr/bin/which: no 
ruby in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
Now that's interesting; rvm info says something completely different:
[root@quackwall bin]# rvm info
ruby-1.9.2-p136:
  system:
    uname:       "Linux quackwall.highwow.lan 2.6.18-194.8.1.v5 #1 SMP Thu Jul 15 01:14:04 EDT 2010 i686 i686 i386 GNU/Linux"
    bash:        "/bin/bash => GNU bash, version 3.2.25(1)-release (i686-redhat-linux-gnu)"

So I have RVM that says one thing and bash which says another. Any suggestions on how to get this working?
