Ah, yes I can reproduce the errors you saw.  As best I can tell, the
generated .hat file has machine words stored in the wrong byte-order.
This means all the internal file pointers are wrong.  They are supposed
to be stored in network (big-endian) order, but your .hat file has them
stored in little-endian order.

The likeliest cause is that your platform does not implement the C-level
htonl() and ntohl() macros/functions correctly.

Can you tell us what machine architecture and operating system you are
using?  You mentioned that installation was difficult.  What did you
need to do that was unusual?
