I think It is not a problem, but if It's not related to OWFS, you may also
post in the brain4home

This not really matter. But note that the state change when the internal
counters are crossing limits, so if set very slow (down to 2Hz) , you may
encounter up to 500ms delay when toggling state.

I installed AE in both ubuntu(9.04) and debian (lenny) with standard flex &
bison packages from distributions.
strange that you don't find the packages within the standard repository.
I simply did:
apt-get install flex
apt-get install bison
apt-get install build-essential
I think that not other package are required, but I will test this on as
fresh ubuntu 9.10 to confirm.

When set as output, the pin follow PIO value regardless of PE & PD values.
1: pin is held up (to vcc) and thus could drain current up to 20mA
(effectively 10mA due to the 470R resistor)
0: pin is held down (to gnd) and thus could sink current up to 20mA (10mA).
