John,

Sorry for my oversimplification, and yes Linux/UNIX is very flexible about
location. My problem with the octave configure script and the sparse
libraries was that ./configure seemed to be looking for things like
/ufsparse/any_header.h instead of just any_header.h. I had header files in
obvious places on my shell path, and the script still couldn't find them. I
had to copy multiple copies of some header files into /usr/local/include/
and /usr/local/include/ufsparse until configure could find them all.

Also, although it isn't part of the sparse matrix libraries, a "make
install" type script that copies all the correct files into whatever is the
correct directory would really aid in octave installation. Are the Florida
sparse matrix folks working in that direction, or is a special octave script
in order?
