I cannot say with certainly what problem was encountered without more
information (architecture and operating system, resulting config.log file,
etc.)  My best guess is that you probably do not have the szip library
installed.  If this is the case, then our configure script is correct in
reporting that the HDF5 library does not work (I assume that was the error.)
  To fix this, you need to download and install the szip library, and if it
is installed in a non-standard place, use --with-szip or LDFLAGS=
appropriately when configuring MOAB.  Alternately, you could just build the
HDF5 library from source w/out support for SZIP compression (MOAB doesn't
use it anyway.)
