petscvariables: hardwired build dir instead of install dir

[Barry Smith]

   Ok, I think I understand your concern,

    This is because the place we want ML to install itself has be
passed in as the true path, it cannot be sent as a symbolic PETSC_DIR
since configure of the subpackage doesn't know PETSC_DIR

   make intall: see the rule in makefile is suppose to replace all  
uses of the
petsc-dir directory with the final prefix installed location: the lines

           sed -i "" 's?$${PETSC_DIR}?TMP_INSTALL_DIR?g' $ 
{INSTALL_DIR}/conf/* ;\
           sed -i "" s?TMP_INSTALL_DIR?${INSTALL_DIR}?g ${INSTALL_DIR}/ 
conf/* ;\

would replace

/repos/hg/petsc/petsc-dev/linux-gnu/include
/usr/local/petsc/2.3.3/linux-gnu/include

Now it could be that the sed is not working when you run install? Can  
you do a
config/configure.py with a --prefix then the make then the make  
install and see what
goes wrong?
