    Status: Answered => Open

Stig Larsson is still having a problem:
Thanks Anders.

Yes, I have an old installation of fenics.  How do I uninstall it?

Yes, I forgot that I should open the terminal using the fenics app.   
In fact, it fails to open with a warning that I am using the wrong  
python.

Johannes also pointed this out.  But how do I change to the correct  
python?

My ~/.profile is

test -r /sw/bin/init.sh && . /sw/bin/init.sh

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

source ~/Work/FEniCS/dolfin-0.9.0/dolfin.conf


I have no  ~/.bashrc. It points to the old fenics.  Regards.  /stig
