Test failures in building the Debian packages for octave-2.9.5

[Rafael Laboissiere]

In building octave-2.9.5 for Debian, several tests failed, most of them
related to sparse matrices.  The log is available at:

    http://pkg-octave.alioth.debian.org/tmp/debian-octave-2.9.5_fntests.log
    
Is there anything I can do to improve the situation?  I am building
against libumfpack4-dev version 4.4-2.

Thanks,
