When you run a script in a subshell, it can modify the environment of
that subshell, then that subshell terminates (when the script is done)
and you get the prompt from your original shell again.  Unlike MS-DOS,
scripts normally run in subshells and can't wreak havoc on your
environment.  If you want to run the script in the current shell, use
one of the following commands :
    . ./.bash_profile
    source ./.bash_profile

This is normal.  Read 'man bash'.  ~/.bashrc is run for
non-login shells.  ~/.bash_profile is run for login shells.  When you
log in you start a login shell, when you run xterm you don't start a
login shell.

What I do is put all config stuff in ~/.bashrc and ~/.bash_profile
looks like this :

# .bash_profile

if [ -f ~/.bashrc ]; then
    source ~/.bashrc
