openscenegraph not installable

[Paolo Cavallini <cavallini@faunalia.it>]

Hi all.

aptitude install openscenegraph
The following NEW packages will be installed:
  libcoin80{a} libopenscenegraph99{ab} openscenegraph
0 packages upgraded, 3 newly installed, 0 to remove and 2 not upgraded.
Need to get 9216 kB of archives. After unpacking 44.3 MB will be used.
The following packages have unmet dependencies:
 libopenscenegraph99 : Depends: libgdal1 (>= 1.8.0) but it is not installable.

Same for osgearth.

Is this a known issue, pending rebuild, or should I open a ticket?
All the best.
