Sorry, I may have confused things by my mistake in a previous response, in 
which I said you shouldn't have to set LD_LIBRARY_PATH.  This is one situation 
where it is necessary to set LD_LIBRARY_PATH:

  - You have a shared library installation in /usr/lib or some other standard
    location where your system looks for shared libraries
  - You have a different version of the library installed somewhere else, 
    which you want to link with

In that case the ld.so dynamic linker will use the installed shared library
unless you have provided the location of the library you want to use instead
in LD_LIBRARY_PATH.  I had never encountered this situation, because I've 
never installed any version of HDF5 in /usr/lib, but once a library is 
installed there, it will be used unless you explicitly tell the system to 
look somewhere else.
