Ah yes, Apple does like to change things superficially. ;-) Back to your problem, if you use --with-clanguage=cxx and --with-cc=gcc (instead of letting the system find it on it's own), then you should provide --with-cxx=g++ (or whatever). If this doesn't work, send configure.log to petsc-maint at mcs.anl.gov. Jed
