    When after unpacking the MOMENT_TENSOR.tar file, 

         cd MOMENT_TENSOR
     cd MECH.NA/0XXXREG/GRD.REG
    Edit the file DOPLTSAC and change the two lines that read 
         YT=`echo $Y0 | gawk '{print $1 - 0.5 }'`
      ....
     Y0=`echo $Y0 | gawk '{print $1 - 1.0 }'`
    to 
         YT=`echo $Y0 | awk '{print $1 - 0.5 }'`
      ....
     Y0=`echo $Y0 | awk '{print $1 - 1.0 }'`

    Now starting at the top, 

         cd MOMENT_TENSOR
     cd MECH.TR/0XXXREG/GRD.REG
    Edit the file DOPLTSAC and change the two lines that read 
         YT=`echo $Y0 | gawk '{print $1 - 0.5 }'`
      ....
     Y0=`echo $Y0 | gawk '{print $1 - 1.0 }'`
    to 
         YT=`echo $Y0 | awk '{print $1 - 0.5 }'`
      ....
     Y0=`echo $Y0 | awk '{print $1 - 1.0 }'`
    The problem was that Ubuntu 11.10 no longer has gawk in the standard distribution. It uses the command 'awk' with the enhanced capabilities. One can obtain gawk by the command 
         sudo apt-get install gawk
    or 
         sudo update-alternatives -s awk /usr/bin/gawk
