i'm using the debian package so this what the people from debian did:

octave2.1 (2.1.53-3) unstable; urgency=low

  * debian/rules: Run configure with DEFAULT_PAGER=pager (Closes:
#230524)
  * debian/control: No longer Depends: on less as /etc/alternatives for
    /usr/bin/pager must be present, and allows user to override locally

  * debian/control: Added "libreadline4-dev, libncurses5-dev,
    libhdf5-serial-dev" to Depends for octave2.1-headers

 -- Dirk Eddelbuettel <edd at debian dot org>  Mon,  2 Feb 2004 18:53:58 -0600

octave2.1 (2.1.53-2) unstable; urgency=low

  * debian/rules: Run configure again --with-hdf5
  * debian/control: Add libhdf5-serial-dev to Build-Depends

  * liboctave/Array-flags.h: Apply patch by Jakub Bogusz which stops
    both a segfault on Sparc and unaligned traps on Alpha.

  * emacs/octave-mod.el: Apply patch by John Eaton to correct octave
mode
    error with very recent XEmacs versions (Closes: #229336)

 -- Dirk Eddelbuettel <edd at debian dot org>  Fri, 30 Jan 2004 23:00:00 -0600

octave2.1 (2.1.53-1) unstable; urgency=low

  * New upstream version 2.1.53 released today

  * This new version contains upstream fixes for the pending Debian
bugs:
    - octave-config echoes an empty path (Closes: #222225)
    - online docs of plot contains non-working example (Closes: #223473)
