Inventor-2.1.5-10

Descritption: Inventor-2.1.5-10 doesn't work on Intel Macs because of endian issues. The symptoms are

1. ivman fails at .../doc/man/man3/ivm/draggers/
2. Binaries that use SoInput, e.g, SceneViewer seg-faults.

The solution is to patch .../lib/database/include/machine.h. The diff is as follows

I cannot verify this yet, as I don't have an Intel Mac, but the fix seems pretty straight-forward. It just needs to be set formatted for inclusion within the port. Thanks for the fix!
