Note: Apart from--download-suitsparse=1 - --with-suitsparse=1 or --with-suitsparse works on ubuntu/linux with preisntalled suitsparse [and presumably will work with other suitsparse installs] And it avoids all the issues with spliting and maintaining our own taballs for UMFPACK, CHOLMOD, and KLU [and managing duplicate copies of dependencies like AMD, COLAMD libsuitsparse etc.] - and will avoid corner-cases like --download-umfpack --with-cholmod-dir= etc.. One caveat: we build only part of suitsparse [required by petsc] - not the whole thing. BTW: should we change PETSC_HAVE_UMFPACK PETSC_HAVE_CHOLMOD etc to PETSC_HAVE_SUITSPARSE? [I don't think its necessary - but checking..] And then configure should print an error message if --with-umpfack option is specified [via check_for_option_changed() in config/configure.py] Satish
