   Satish,

   We should fix the PETSc BLAS/LAPACK configuration (BuildSystem) to not "have conflicts with macports blas/lapack" by, for example, to use the Apple BLAS/LAPACK if the macports one fail. That is, we shouldn't tell people not to use macports, we should have a configuration system robust enough to handle macports problems. Is this a problem we can reproduce? and hence debug? and hence fix?
