Adding MrSid support
Geoapt uses GDAL. So all you need to do to add MrSid support to Geoapt, is to add MrSid support to GDAL.
Complete instructions for Ubuntu are here: http://trac.osgeo.org/ubuntugis/wiki/UbuntuGISRepository
As part of this process I added the "unstable" GIS repo and updated all my existing GIS packages to the latest versions.
I had to become a LizardTech developer to download the SDK. If you want MrSid support, you do too. This means giving them your contact info and promising not to give anyone compiled copies of the GDAL plugin.
The above instructions worked, I now have a MrSID enabled gdal.
After restarting Geoapt and testing, I find I now also have MrSid support in GeoApt. YAY!!
