Re: ./configure does not recognize umfpack library.

Dmitri,

Octave 2.9.x builds fine without UMFPACK, but can't solve full sparse 
equations, though with the use of the LAPACK tridiagonal and banded 
solvers and code for back substitution for triangular matrices it can 
still solve many cases... Try

a = 100*speye(100,100) + sprandn(100,100,0.05);
[l,u,p] = lu (a);

and I'll bet you get an error, since the LU function won't find UMFPACK 
and will fail with an error...

Cheers
David
