I can confirm correctness of the fix (done myself exactly the same, then discovered this bug). Please include this patch into next octave ebuild revision as "USE=sparse" is very important for many uses of octave.
Hello, any news?
(In reply to comment #5) Patch works for me, and PLEASE add it to portage quickly or cause tons of duplicate bugs reports. :)
This was fixed in later releases. #264757 is the version bump request bug, once octave is at 3.0.5 or even 3.2 this here can be closed.
This should be fixed in octave-3.2 which just hit the tree. Please re-open if the problem persists. Thanks, Markus
