Unable to update my Bash in Mac by MacPorts

I updated unsuccessfully my Bash to 3.2.48 by MacPorts.

It seems that I do not have it active, since I get

echo $BASH_VERSION
3.2.17(1)-release

How can you make the newest Bash active such that I get it for my login shell?

You can switch your login shell, from your existing Mac OS X login shell (by default its /bin/bash shipped with Mac OS X), to MacPorts /opt/local/bin/bash just by using the following shell script:

#!/opt/local/bin/bash
if [ `grep /opt/local/bin/bash /etc/shells` ]; 
then 
    echo /opt/local/bin/bash | chsh -s /opt/local/bin/bash;     
else 
    echo /opt/local/bin/bash | sudo tee -a /etc/shells; 
    chsh -s /opt/local/bin/bash; 
fi

Run the following code, for instance to change your shell to the newest Bash installed by MacPorts 

chsh -s /opt/local/bin/bash

If that gives you the message,

"non-standard shell"

you will need to add 

/opt/local/bin/bash

to 

/etc/shells

Note that /etc/shells is just a text file, so you can edit it directly if you authenticate as root. You can programmatically change it by the command

sudo -s
Password:
# echo /opt/local/bin/bash >> /etc/shells

If your first chsh command failed, run it now again if you managed to change the above file.

I'm guessing it's installed but not being used as your login shell.

You can change the shell using dscl on the command line.

At the dscl prompt type the following:

list Local/Default/Users
read Local/Default/Users/<your username here>
change Local/Default/Users/<your username here> UserShell /bin/bash /opt/local/bin/bash

I have another example of dscl use on my blog if it helps.
