svn commit: r427405 - head/math/octave-forge-interval/files

[Stephen Montgomery-Smith]

Author: stephen
Date: Tue Nov 29 23:01:49 2016
New Revision: 427405
URL: https://svnweb.freebsd.org/changeset/ports/427405

Log:
  - Another attempt to get port to build on FreeBSD <=9.
  - No portrevision bump, because I don't believe this change will effect the
    final result on other OS versions.
