It is currently in the branch shri/update-SuiteSparse https://bitbucket.org/petsc/petsc/branch/shri%2Fupdate-SuiteSparse. This change downloads the entire SuiteSparse package and installs all the sub-packages that PETSc currently supports (UMFPACK, CHOLMOD, and KLU). We can of course have selective installation of sub-packages if need be, currently it does not. I know you prefer a 'separate' configure script for each sub-package, but we think a single configure is a better approach. This change also updates PETSc to use the latest SuiteSparse. I've tested it with both debugging and optimized modes (with complex and 64-bit ints) and there was no change needed for UMFPACK or CHOLMOD solver interfaces. Let us know what you think? petsc-devs?

Those packages were never packaged for sane independent-install anyway.

However, some distributions have done the work of allowing separate
install of each component.  Could we have the one suitesparse configure
script detect which components are available?
