[petsc-dev] Why is -I$PETSC_DIR/src/dm/mesh/sieve in CLINKER even when configured without Sieve?

PETSC_DIR/src/dm/mesh/sieve is coming from examples/tutorials/makefile
[not configure] - so its always there - irrespective of sieve. [the
public includes should never be in src - so this does need fixing]

-I/usr/lib -I/usr/include [and perhaps -L/usr/lib] are the artifacts
of '--with-hdf5-dir=/usr --with-parmetis-dir=/usr' etc..

I guess garbage in garbage out here. [not sure if configure should
overide user speified wish here..]

This must be coming from your MPI install. I suspect
/usr/local/include is also from there.  check 'mpicc -show' and
'mpif90 -show'. Configure.log will have details.

The additonal stuff is the language inter-operability sutff - and some
of the external package dependency stuff.
