I've uploaded a new Fink package for SuiteSparse to the package

When present during an Octave build, Octave will use SuiteSparse
for many calculations using sparse matrices.
This is my 1st attempt to creating a package. The package validated
fine. However, I'm still expecting some things may need correcting
or improving.
Is this intended to modify how octave builds? If so that's contrary
to Fink policy unless a separate variant of octave is made to use it.

Modify how Octave builds? .... hmmm, depends upon perspective
(meaning I'm not sure).
The presence of SuiteSparse doesn't modify how Octave builds any more
than the packages for fftw, qhull, readline5, gnuplot, etc. Octave
would build and function fine (except for the absent
functionality) ... actually ... it *would* build and function if not
for the dependencies stated in octave.info.
There is no need to modify octave.info or octave.patch (names?) in
order for SuiteSparse components to be included in Octave's
functionality. When SuiteSparse is installed, Octave's usual
configure process will recognize that SuiteSparse is available and
produce a makefile that links to it.
When Octave is configured, the *present* process produced this
snippet ...
----------------------
Octave is now configured for i386-apple-darwin
Source directory: .
Installation prefix: /sw
C compiler: gcc -mieee-fp -Wall -W -Wshadow -g -O2
C++ compiler: g++ -mieee-fp -Wall -W -Wshadow -Wold-
style-cast -g -O2
Fortran compiler: /sw/bin/g95 -O2 -mieee-fp
Fortran libraries: -L/sw/bin/../lib/gcc-lib/i386-apple-
darwin8/4.0.3 -lf95
BLAS libraries: -framework vecLib
FFTW libraries: -lfftw3
GLPK libraries: -lglpk
UMFPACK libraries:
AMD libraries:
CAMD libraries:
COLAMD libraries:
CCOLAMD libraries:
CHOLMOD libraries:
CXSPARSE libraries:
HDF5 libraries: -lhdf5
CURL libraries: -lcurl
REGEX libraries: -lpcre
QHULL libraries: -lqhull
LIBS: -lreadline -lncurses -lhdf5 -lz -lm
Default pager: less
gnuplot: gnuplot
----------------------
When SuiteSparse is present, the missing modules (UMFPACK, AMD, CAMD,
COLAMD, CCOLAMD, CHOLMOD, and CXSPARSE) are found and linked to
during the build.
My impression is that SuiteSparse is usually included in an Octave
build, and should be a dependency of Octave if full functionality is
desired.
Thoughts?
