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.
