Hi Prabath,

this is a problem with your OpenDX installation, not with Cactus. It 
appears that the HDF5 import modules have been built with an HDF5 1.6.4 
installation but when you start OpenDX it finds a shared libhdf5.so 
library of version 1.6.3. HDF5 does a versions check at runtime and by 
default will abort the program if they don't match.

You could set HDF5_DISABLE_VERSION_CHECK as the message suggests but I 
recommend that you fix your HDF5 installation instead: just make sure 
that the 1.6.4 shared HDF5 library is found by the system loader first 
(either by setting LD_LIBRARY_PATH or adding the HDF5 libdir to 
/etc/ld.so.conf).
I also recommend uninstalling the older HDF5 version 1.6.3 then.
