The pgplot library might be great stuff, but the license is
incompatible with the GPL, so it can't be linked and distributed with
Octave.  The pgplot web pages say:

  PGPLOT is not public-domain software. However, it is freely
  available for non-commercial use. The source code and documentation
  are copyrighted by California Institute of Technology, and may not
  be redistributed or placed on public Web servers without
  permission.  The software is provided ``as is'' with no warranty.

Both the non-commerial use and no redistribution clauses are problems.
