Virtual package depending on latest 64-bit PETSc development package

 PETSc is the "Portable Extensible Toolkit for Scientific Computation", a suite
 of data structures and routines for the scalable (parallel) solution of
 scientific applications modeled by partial differential equations. It employs
 the MPI standard for all message-passing communication. Several sample
 scientific applications, as well as various papers and talks, demonstrate the
 features of the PETSc libraries.
 .
 This metapackage installs libpetsc64-real-dev, which will always
 depend on the most recent version of PETSc with real number support
 and 64-bit indexing. So if you install it then you will get upgrades
 automatically.
