Roy, Yes, the problem was with PETSc's makefile. It existed in the early versions of petsc-3.3, but was fixed by one of the early patches: https://bitbucket.org/petsc/petsc-dev/diff/makefile?diff2=a0fe59a5123c&at=default I was running the latest petsc-3.3 and petsc-dev everywhere _except_ the machine in question, which prompted me to blame the machine. Without the fix above make -C $PETSC_DIR -s getincludedirs and similar will fail, if run from anywhere other than $PETSC_DIR.
It looks like the problem was short lived (introduced here: https://bitbucket.org/petsc/petsc-dev/diff/makefile?diff2=5f84ba60b4ac&at=default), so libmesh configure probably needn't worry about it.
