I tried this commandline but all I've got was an error:

        Using from definition: proj=wgs84 datum=WGS84
        Rel. 4.4.9, 29 Oct 2004
        projection initialization failure
        cause: unknown projection id
        program abnormally terminated

Do you know what might be the problem?

Thanks for the help.
