Unable to upgrade from eDirectory 8.7.3.10 to eDirectory 8.8.X on AIX without uninstalling exiting components

When trying to run nds-install and upgrade from eDirectory 8.7.3.10 to 8.8.X:

%%% Novell eDirectory components are already installed on your system. Please uninstall all the components of the existing installation and then proceed with this installation.

The nds-install script is not correctly parsing the currently installed version.

Please modify this section of the nds-install script:

AIXcheckForPackageExistence()
{   pkg=$1
    version=0
    lslpp -l $pkg  >> $log_file 2>&1
    if [ $? = 0 ]
    then
      pkg_exists=1
      version=`lslpp -L  | grep -w $pkg | cut -c30-36` >/dev/null 2>&1
    else
      nameConverter $pkg
      lslpp -l | grep  $pkg  >> $log_file 2>&1
        if [ $? = 0 ]
        then
          pkg_exists=1
          version=`lslpp -L  | grep -w $pkg | cut -c30-36` >/dev/null 2>&1
        else
          pkg_exists=0
        fi
    fi

So that "cut -c30-36" is cut -c29-36"  

The code should then look like:

AIXcheckForPackageExistence()
{   pkg=$1
    version=0
    lslpp -l $pkg  >> $log_file 2>&1
    if [ $? = 0 ]
    then
      pkg_exists=1
      version=`lslpp -L  | grep -w $pkg | cut -c29-36` >/dev/null 2>&1
    else
      nameConverter $pkg
      lslpp -l | grep  $pkg  >> $log_file 2>&1
        if [ $? = 0 ]
        then
          pkg_exists=1
          version=`lslpp -L  | grep -w $pkg | cut -c29-36` >/dev/null 2>&1
        else
          pkg_exists=0
        fi
    fi

This will then get a complete 8.7.3.10 instead of .7.3.10
