External Email - Use Caution

Hello Alex, I would try unseting LD_LIBRARY_PATH altogether or at least take the matlab paths out of it.  My understanding is freesurfer commands don't need matlab paths in LD_LIBRARY_PATH to use matlab after you have setup the freesurfer environment (set FREESURFER_HOME, and source’d the freesurfer setup script).   It looks like the matlab libraries in LD_LIBRARY_PATH are overriding other binaries trying to find the system libc with the symbols they need (and are instead finding the matlab copy of the system libraries). - R.
