I don't know of such a compile yet, but I bet that there are some people around here who should be capable of doing so... I regret that I can't help you out personally and I fear you'll have to be pacient, but sooner or later (and if you nag ppl long enough
) I see a pretty fair chance for a 64-bit compile.
(Not that I had the slightest idea in what way a 64-bit compile differs from a 32-bit compile, and if the changes are hard to make, but as I said: Sooner or later, some of our linux "gurus" are bound to have a look at your thread.)
