Yea.  It's possible that those are not true DRG files, but DRG-E
(enhanced).  If they are modified from what the USGS originally
distributed, either by chopping off the map collars or by using
MrSID compression, Xastir won't work with them.

Another possibility is that you may have installed
libproj/libgeotiff in the incorrect order or via some method that
was not per the installation instructions in README.1ST.

Can you get a plain vanilla USGS geoTIFF topo to display?  If not,
go back and reinstall libproj and then libgeotiff per instructions
and try again.
