help help bash. No more Terminal on Mac OS X

[True Logik]

Hello,

Please help or tell me where I can find help. yesterday evening I 
installed BASH v2.05 from the website:

http://www.osxgnu.org/software/Shells/bash/

Since then I cannot even open a Terminal in X11. This is a MAJOR 
DISASTER!

Is there a way to de-install BASH or set my system back to the way it 
was before the install? I really need a working Terminal... :-(

My system: MAC OS X Version 10.3.8 Build 7U16 on a dual G5 PowerPC.

I can open, but not use, the Console program, I get no prompt! However 
I do get the follwing output on the console:
