Maybe you could try with homebrew?

The only thing I can think for the precompiled binary is to attach a debugger to it.  h5mma should be loaded when you load SimulationTools; it will appear as a process in "ps".  You could attach gdb:

/opt/local/libexec/gnubin/gdb --pid $(pgrep h5mma)

and then type "continue".  Now, evaluate the ImportHDF5 expression from Mathematica. With any luck, you will get a backtrace in gdb when h5mma crashes.  I wonder if the problem is related to the executable being compiled on an earlier version of OS X.
