Sounds like openct should use virtual/dev-manager vs a hard-coded udev
dep. But then again there is probably a reason that the dev opted to use
>=0.96, so you should probably read the ChangeLog and dig around to
perhaps see why. It could be something as  simple/silly as gentoo
providing an init script to go along with it.

You should file a bugs for both the libtool problem and the openct
problem with the respective maintainers. Feel free to CC: embedded@ on
the bug.
