I was just digging around in the libftpio source code. It does only check
to see if the FTP_PASSIVE_MODE environment variable is defined at all. I
made this small patch to it that I think makes enough sense almost to have
it comitted. With this patch it makes libftpio also understand the
YES or NO value of FTP_PASSIVE_MODE. It's a diff against
src/lib/libftpio.c rev 1.33 from 4.0-STABLE. Check out this patch and let
me know if it works for you. The if statements could probably be cleaned
up a little :), but it works.
