How too find a dependence package...???

[larry]

I am looking for two dependence packages that are needed to run the 
Xastir program...
Can anyone tell me if there is a way to search for Geotiff & Gdal/OGR 
from Ubuntu's list of packages, also they maybe spelled 
differently...Since I can not find them just maybe there are some Ham 
operators using Xastir that could also help me with this, any help would 
be appreciated...Thanks

Larry
