To install the pkgutils package, download pkgutils-1.6.21.pkgadd.tar and install as follows (assumes the file was downloaded to the /tmp/pkgutils directory):
  $ /bin/su
  # cd /tmp/pkgutils
  # tar xf pkgutils-1.6.21.pkgadd.tar
  # pkgadd -d . TWWpkgutils16c TWWpkgutils16m TWWpkgutils16u

If using RPM packages on non-Redhat Linux platforms rather than packages in the native package format, the RPM pkgutils package must be installed rather than the native-format version of the pkgutils package (detailed in the instructions above). Download pkgutils-1.6.21.rpm.tar and install as follows (assumes the file was downloaded to the /tmp/pkgutils directory):
  $ /bin/su
  # cd /tmp/pkgutils
  # tar xf pkgutils-1.6.21.rpm.tar
  # rpm [--dbpath /opt/TWWfsw/.rpmdb] -Uv TWWpkgutils16*.rpm
