[petsc-dev] ccache tips?

[Matthew Knepley]

I configured MPI with CC="ccache gcc"

knepley/feature-dm-remove-hybrid *$:/PETSc3/petsc/petsc-dev$
/PETSc3/petsc/bin/mpicc -show
/Users/knepley/MacSoftware/bin/ccache gcc -Qunused-arguments
-fstack-protector -Qunused-arguments -g3 -Wl,-flat_namespace
-I/PETSc3/petsc/include -L/PETSc3/petsc/lib -lpmpich -lmpic
h -lopa -lmpl -lpthread

and then used --with-mpi-dir. This is the way to go if you do multiple
ARCHes. Have not had a problem on OSX or Linux. Works with all packages.
