yes, I have the /Applications/freesurfer/lib/gcc directory.(actually, ‘had’ as I reinstalled 5.3)   I installed 6.0 on top of 5.3 without uninstalling 5.3 first, so it was not a clean install.  I will try a clean re-install with the tar file with the steps you suggest. Thanks.

Hello Fred,

Do you have the /Applications/freesurfer/lib/gcc directory? Also, out of
curiosity, did freesurfer 5.3 exist on your system before installed 6.0?
That error shouldnt happen if FS6 is cleanly installed and definitely
shouldnt happen of SIPS is disabled.

I suppose as a last resort could you just completely remove FS from your
machine and just install it directly from the tar file (save the
license.txt file):

 ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0/freesurfer-Darwin-OSX-stable-pub-v6.0.0.tar.gz

 $> cp /Applications/freesurfer/license.txt ~
 $> sudo rm -rf /Applications/freesurfer
 $> sudo tar -C /Applications -xzvf
freesurfer-Darwin-OSX-stable-pub-v6.0.0.tar.gz
 $> sudo mv ~/license.txt /Applications/freesurfer/
