Junky summary of me running #lambdaMOO myself on a 64 bit system.
Simple details such that you can do exactly what I have done. Debugging mood, not a high-quality-writing mood.
The 32/64 database problem I think is that the change in integer width broke some listutils, which trivially stops @create and @dig working (important ones!) because the map_args over the aliases errors.
tl;dr
@edit #21:set_names
del #14
ins "return {name, {}};"
