I am against additional checks, which are always fragile and provoke more
pain than they dismiss. However, we
can improve the error message. After the 'conf' check, we remember that the
library should be installed. If its not
found, we can

  a) have a nice error that says "it looks like you deleted 'lib'. Please
remove $PETSC_ARCH and rerun configure"
      with a picture of a paperclip.

  b) delete the parmetis file in 'conf' and call install again.

What most experimenters take for granted before they begin their experiments
is infinitely more interesting than any results to which their experiments
lead.
