[Qgis-user] building gdal for mrsid

[Don Harter]

OK thank you.  I can use checkinstall to create a .deb package.  Perhaps 
with a careful choice of options and dependencies I could replace the 
ubuntugis package.  With wrong dependencies  my ubuntu system was broken 
and I had problems installing packages.  It wanted me to "fix" the mess, 
but I would have had to delete some packages that I wanted to keep.
