Hello, yes. There's only one version/instance of gdal running on the machine. 

Thanks,

MapServer is unable to read the raster and display it.   However, GDAL is able to read (gdalinfo, etc), translate (gdal_translate), transform (gdalwarp) the raster. Any ideas how to solve this?  MapServer is compiled with GDAL support and everything looks OK. The "gdalinfo --formats " command shows the format is supported.
