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, -- Rafael
