Problem with gdal_vrtmerfe (was:Re: [Qgis-user] combining individual tif files into a multiband tif file)

[Agustin Lobo]

I run:

alobo at alobo-laptop:~/CHINA$ ./gdal_vrtmerge.py -separate -o tm2.vrt *.tif

and get:
./gdal_vrtmerge.py: line 1: !DOCTYPE: No such file or directory
./gdal_vrtmerge.py: line 2: PUBLIC: command not found
./gdal_vrtmerge.py: line 3: syntax error near unexpected token `newline'
./gdal_vrtmerge.py: line 3: ` 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">'

I'm using ubuntu hardy, have gdal and FWTools 2.0.6
(i.e. gdal_merge.py works fine)

Is there anything I have to do in order to install gdal_vrtmerge.py ?

Thanks

Agus
