'XYZ' probably isn't a 64-bit LSB-first ELF file.

Solution: Install both chrpath.x86_64 and chrpath.i686 !

$> sudo yum install chrpath.x86_64

You might also need to only install i686 version. For that first remove the one above:

(1) $> sudo yum remove chrpath
(2) Download this : http://dl.atrpms.net/el6-i386/atrpms/stable/chrpath-0.13-5.el6.i686.rpm
(3) $> sudo rpm -ivh chrpath-0.13-5.el6.i68

Problem :

You might have a build error like this :

chrpath -r `readlink -f arch/linux-i686/thelib`:`readlink -f ../arch/linux-i686/stage/opt/haivision/lib` arch/linux-i686/crtmpserver/crtmpserver
`arch/linux-i686/crtmpserver/crtmpserver' probably isn't a 64-bit LSB-first ELF file.
