I believe that the current version, while working on 64bit architectures
is really 32-bit in practice (i.e. it uses ints as indexes, therefore
limiting data structures to 2GB).  Clinton Chee at the UNSW HPC group
has patches he's trying to get into the main tree.  I'm not sure of the
status of this, but I do know he has the test-suite passing on an SGI
Altix.  More information here: http://tinyurl.com/amsrh
