Octave-2.9.9 luinc failure

[Tom Holroyd (NIH/NIMH) [E]]

I got this for make check on two different machines, neither has sparse matrix 
stuff built 'cause the libraries aren't there. Would that explain this?

Integrated test scripts:

 src/DLD-FUNCTIONS/cellfun.cc ........................... PASS   29/29  
 src/DLD-FUNCTIONS/conv2.cc ............................. PASS    1/1   
 src/DLD-FUNCTIONS/dispatch.cc .......................... PASS   13/13  
 src/DLD-FUNCTIONS/luinc.cc .............................panic: Segmentation fault -- stopping myself...
make[2]: *** [check] Segmentation fault

Running luinc() by hand various ways produces things like
octave:3> a = sparse(a);
octave:4> [l,u,p,q] = luinc(a, struct('droptol',0));
error: UMFPACK not installed

so I'm unsure how to test this.
