It's important that you download and build PETSc yourself. The
Ubuntu/Debian packages have been broken for a long time (at least
every time I've tried). If you build PETSc yourself, you can also ask
PETSc to build Hypre (which gives you AMG).

Here's a simple howto:

1. Build and install OpenMPI from www.open-mpi.org

2. Unpack PETSc in /usr/local/lib and rename to petsc (or make
symbolic link)

3. cd petsc; export PETSC_DIR=`pwd`

3. 

./config/configure.py --with-clanguage=C++ --with-shared=1 --download-hypre=yes --download-umfpack=yes --with-mpi-dir=/usr/local

make all
