[MINC-users] minc2, hdf5, and shared libraries

As a first off dirty hack I would try:

(4) Either drop back to MINC 1.X or compile MINC2 without HDF support
(configure --disable-minc2) and see if this really is an issue with
HDF or MINC.

Once you know this then I would try removing MINC and seeing if HDF5
breaks in the same way just by itself. If it does then you really only
have one option (1). Or add the call as per (2), I would punt that
there might not be complete memory clean up though.
