To install the pkgutils package, download pkgutils-1.6.21.lpp.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.lpp.tar
  # installp -acqQ -d /tmp/pkgutils/TWW.pkgutils16.bff TWW.pkgutils16

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
