1. Download and extract into the directory /usr/local
2.export FREESURFER_HOME=/usr/local/freesurfer

Its fine, but when I run this step

3.source $FREESURFER_HOME/SetUpFreeSurfer.sh

I receive this message n time

-------- freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0 --------
Setting up environment for FreeSurfer/FS-FAST (and FSL)

and I must press Ctrl+C to stop.
What do I do now?
