As suggested, I have modified the .csh file (since the last version does not have a .cshrc file).
I have edited according with my current directories, but when I try

source $FREESURFER_HOME/SetUpFreeSurfer.csh

I get the following:

-------- freesurfer-Darwin-snowleopard-i686-stable-pub-v5.3.0 --------
Setting up environment for FreeSurfer/FS-FAST (and FSL)
WARNING: /Application/freesurfer//Applications/freesurfer/subjects does not exist
FREESURFER_HOME   /Applications/freesurfer/
FSFAST_HOME       /Applications/freesurfer//fsfast
FSF_OUTPUT_FORMAT nii.gz
SUBJECTS_DIR      /Application/freesurfer//Applications/freesurfer/subjects
MNI_DIR           /Applications/freesurfer//mni

The editing I made to the .csh file are the following:
 
 setenv FREESURFER_HOME  /usr/local/freesurfer/stable5-pub 
CHANGED TO:
setenv FREESURFER_HOME /Applications/freesurfer/
endif

setenv SUBJECTS_DIR $FREESURFER_HOME/subjects
endif
CHANGED TO:
setenv SUBJECTS_DIR $FREESURFER_HOME/subjects
endif

Many thanks,
Pablo
