- Hm - 'make all' prints instructions for 'make install':

=========================================
gmake[1]: Leaving directory `/home/balay/petsc'
Now to install the libraries do:
make PETSC_DIR=/home/balay/petsc PETSC_ARCH=arch-mpich install
=========================================

- And 'make install' prints instructions on 'make test'

$ make PETSC_DIR=/home/balay/petsc PETSC_ARCH=arch-mpich install
*** Using PETSC_DIR=/home/balay/petsc PETSC_ARCH=arch-mpich ***
*** Installing PETSc at prefix location: /home/balay/tmp/petsc-install  ***
====================================
Install complete. It is useable with PETSC_DIR=/home/balay/tmp/petsc-install [and no more PETSC_ARCH].
Now to check if the libraries are working do (in current directory):
make PETSC_DIR=/home/balay/tmp/petsc-install test
====================================

- With the above instructions - make test works - but with a minor error.

$ make PETSC_DIR=/home/balay/tmp/petsc-install test
Running test examples to verify correct installation
Using PETSC_DIR=/home/balay/tmp/petsc-install and PETSC_ARCH=arch-mpich
C/C++ example src/snes/examples/tutorials/ex19 run successfully with 1 MPI process
C/C++ example src/snes/examples/tutorials/ex19 run successfully with 2 MPI processes
egrep: /home/balay/tmp/petsc-install/arch-mpich/include/petscconf.h: No such file or directory
Fortran example src/snes/examples/tutorials/ex5f run successfully with 1 MPI process
Completed test examples
=========================================
Now to evaluate the computer systems you plan use - do:
make PETSC_DIR=/home/balay/tmp/petsc-install PETSC_ARCH=arch-mpich streams NPMAX=<number of MPI processes you intend to use>


- This can be fixed with using PETSC_ARCH='' - Yeah - using both build
makefiles and install makefiles has too many corner cases - but I'm not sure
if there is a better way..

$ make PETSC_DIR=/home/balay/tmp/petsc-install PETSC_ARCH='' test
Running test examples to verify correct installation
Using PETSC_DIR=/home/balay/tmp/petsc-install and PETSC_ARCH=
C/C++ example src/snes/examples/tutorials/ex19 run successfully with 1 MPI process
C/C++ example src/snes/examples/tutorials/ex19 run successfully with 2 MPI processes
Fortran example src/snes/examples/tutorials/ex5f run successfully with 1 MPI process
Completed test examples
=========================================
Now to evaluate the computer systems you plan use - do:
make PETSC_DIR=/home/balay/tmp/petsc-install PETSC_ARCH= streams NPMAX=<number of MPI processes you intend to use>


Note: the primary fix is to specifying 'PETSC_DIR' & PETSC_ARCH from
command line to 'make' to override the defaults in conf/petscvariables
