There could be two problems:  One:  You might not have installed
libproj and libgeotiff correctly.  They have to be installed in the
correct order and there's an extra file that has to be exploded in
the proj/nad directory as well.

Two:  You might have a MrSID compressed geotiff, or you might have
some other form of "DRG-E" file, instead of a real DRG file.

Try to "display" the file or run "xv" on it.  If you can see the TIFF
image and it has a nice wide white border around it, you've probably
got a real DRG.

Try the geotiff files at http://wetnet.net/~we7u/xastir to see if you
can bring them up ok in Xastir.  Those are real DRG's.
