[Qgis-user] Error Loading GDAL Plugin

[alt-shn]

Hi!

My name is Andre Mano, and i'm carrying a project on paleontological
sites in western Portugal, and i'm using QGIS. The overaal experience
has been great, however I came across a problem I don't know how to
solve.

When I try to load GDAL tools plugin i get the following error message: 

"The plugin depends on some components missing on your system. You need
to install the following Python module in order to enable it: osgeo"

What component is this? I'm using ununtu 9.10 with QGIS 1.4. Presently I
only have on GIS repository active - ubuntu unstable.

Can someone help me please?

Thank You!

André Mano
