This error typically happens when you try and run a 64-bit executable on a 32-bit system. From your later posts, you are clearly running the 64-bit FS:

-------- freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0 --------

The question now is, is your base system 32 or 64-bit?There are many ways to ascertain this. One simple one is to type $>file /sbin/init which on a 64 bit system returns: /sbin/init: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped and on a 32-bit system returns: /sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped Please verify your base system "bit"ness.
