strange package dependencies

[Christoph Groth <cgroth@gmx.net>]

Hi,

My Linux box is running an up-to-date potato and everything seems to
work just fine, however there is one thing I don't understand:

My little brother wants some jump'n'run game so I would like to
install xtux.

`apt-get -s install xtux' says:

Reading Package Lists... Done
Building Dependency Tree... Done
The following extra packages will be installed:
  libesd0 
The following packages will be REMOVED:
  libesd-alsa0 
The following NEW packages will be installed:
  libesd0 xtux 
0 packages upgraded, 2 newly installed, 1 to remove and 0 not upgraded.
Remv libesd-alsa0 [esound-alsa ]
Inst libesd0
Inst xtux
Conf libesd0
Conf xtux

So apt wants to replace libesd-alsa0 with libesd0.  But why?  Sure,
xtux depends on `libesd0 (>= 0.2.14-0.2)' but `libesd-alsa 0.2.17-7'
which is installed provides `libesd0'.  What is the point in replacing
`libesd-alsa 0.2.17-7' with `libesd0 0.2.17-7'?

Any claryfing comments are welcome!


Thanks,

Christoph
