I don't see the problem, these pointers are not depending on
each
other. Or are you saying that it leaves your tree dirty? Because
that has not happened to me and I believe others did not have a
problem with it either, otherwise this would happen a LOT of times.
'built twice' means 'build same source on different hosts at different
times'. I want to get reproducible build results for binary packages.

I don't know that much about perl myself and I don't quite get it from
the genprotocol.pl, but you could sort the output before printing, for
sure. But I'm still more curious about how come that causes you
something that's not happening for me.
I'm sure it returns reproducible results on localhost. But even if it
did not noone would notice because if the file happens to differ it will
just get rebuilt.
