Yes, I was. DOLFIN needs to figure out where to find PETSc and it then
uses the getincludedirs flag with make to get the correct flags.

If possible, I would rather do a 'make install' in PETSc like with any
other library (without needing to set PETSC_DIR to something special),
but then I don't know how to get compiler flags and link libraries
correctly. It would be nice to have a petsc-config script (like
gtk-config, xml2-config, dolfin-config, etc) that spits out the flags.

If someone has any better suggestions for how to compile against PETSc,
please send me a patch. Only the the PETSc specific part in
configure.ac for DOLFIN would have to change.  (If you edit this file,
then run ./scripts/preconfigure and then ./configure.)
