and after I run /bin/bash, I have a different behavior

[email protected] [~]# /bin/bash
[email protected] [~]# rails -v
Rails 3.2.8
[email protected] [~]# rvm info

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

Anyone has an idea what's going on and how can I fix this issue?

Thanks

Here are my .bashrc and .bash_profile file contents

[email protected] [~]# cat ~/.bashrc
# .bashrc

# User specific aliases and functions

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

    export HPATH=/home3/user1/
    export GEM_HOME=$HPATH/ruby/gems
    export GEM_PATH=$GEM_HOME:/usr/lib64/ruby/gems/1.8
    export GEM_CACHE=$GEM_HOME/cache
    export PATH=$PATH:$HPATH/ruby/gems/bin
    export PATH=$PATH:$HPATH/ruby/gems  

PATH=$PATH:/home3/user1/.rvm/bin # Add RVM to PATH for scripting

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[email protected] [~]# cat ~/.bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME


[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

This looks like a path issue to me. When you run rails the first time, it's finding a global rubygems installation before your local rvm copy.

After you run /bin/bash from the command line, you are starting an interactive shell, which sources (executes) ~/.bashrc. My guess is that that contains the rvm initializations that are failing to run when you login with a login shell.

Take a look at ~/.bash_profile and ~/.bashrc. Here is what the latest RVM installer generates:

$ cat ~/.bashrc
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting

$ cat ~/.bash_login 
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
export NODE_PATH=/usr/local/lib/node_modules
if [ -f ~/.bashrc ]; then
   source ~/.bashrc
fi

If this is what you've got, then you're somehow logging in through an interactive shell and not a login shell (how???). You should be able to fix both issues with source ~/.bash_profile (.bash_login in OS X).
