Yes, it was on sarge.
But this dependency is satisfied on sarge with hotplug version
included. So it seems not ok.

This is what I done, but I had to discover it by myself, because the
dependency was satisfied by hotplug.
Is hotplug too old on Sarge ?

No, if I recall correctly, I had to upgrade it. But I think I did not
try to use only hotplug instead of udev. I know that I wanted udev
installed.

Maybe there is no problem currently, but since I had some troubles with
your packages and udev/hotplug last week end, I prefer to tell it right
now. ;-)

Anyway this is only a Sarge issue.

Could be fine, but in fact we have to follow unstable, not really sarge ;)

Fine ! ;)

Really really really clever.
Having a build-dep on hotplug or udev is ugly I think. (I did not see this).
Furthermore, hotplus is now provided by udev, IIRC.
