Joe,

The autoconf macro that searches for the headers is

  AC_CHECK_HEADERS([ufsparse/umfpack.h umfpack/umfpack.h umfpack.h],
<found>, <not found>)

where AC_CHECK_HEADERS is a standard autoconf macro. So the header in
order will look n <include_dir>/ufsparse/umfpack.h,
<include_dir>/umfpack/umfpack.h and <include_dir>/umfpack.h. So if it
did it seems autoconf on your system has a problem.

Yes, the UMFPACK,CXSparse,COLAMD have to be installed within the
umfsparse/ directory. This could be located within /usr/include or
/usr/local/include .  I put it under the latter directory and the
configure script finds it. Unfortunately, the compilation of UMFPACK
doesnt work. Looks like rpms are the only solution. 
Would it make sense to include these packages in octave itself in the next version/release?
