As a matter of fact, I do, and here it is. I think I tried this and it 
built correctly, and octave 2.9.x was able to link to it. This is a case 
of the developer not taking the time to offer options like building 
dynamic libraries, so packagers unfortunately have to do it themselves. 
My spec file was based on Debian, which I think is the only distribution 
that has packaged UMFPACK so far (it's clearly only for a small niche of 
users). On a non-RPM-based distribution, I would think all you need is a 
build script that duplicates the %build and %install parts of the spec 
file. I will eventually try to get this into Fedora Extras, but my short 
term priority is to get octave 2.1.x and octave-forge in with all their 
dependencies before I worry about 2.9.x and its new dependencies, so 
don't count on it right away.

%description
UMFPACK is a set of routines for solving unsymmetric sparse linear
systems, Ax=b, using the Unsymmetric MultiFrontal method. Written in
ANSI/ISO C, with a MATLAB (Version 6.0 and later) interface.

The new code is typically faster than V2.2.1, uses dynamic memory
allocation, and has a symbolic preordering and analysis phase that
also reports the upper bounds on the nonzeros in L and U, flop count,
and memory usage in the numeric phase. It includes a Matlab
interface. V4.x is for real and complex matrices, rectangular and
square, and both non-singular and singular.
