Ok so I figured out how to get ECW support for Ubuntu but I don't know enough about linux to get it to run.

Here is what I need to understand:

-Where does GDAL's stuff reside on my filesystem?
-How does QGIS (Quantum GIS) use GDAL?
-How do I use the ERMapping ECW SDK to compile it with GDAL to get a GDAL that has ECW? Basically how to I get a GDAL with ECW support?

If someone can answer or help me with this then I would gladly help getting a package out for the Ubuntu Semantic Package Manager so it is a lot easier to get ECW support.
