  configure.in:292: error: AC_SUBST: `pcp_owner pcp_group' is not a valid
  shell variable name
  configure.in:292: the top level
  autom4te: /usr/bin/m4 failed with exit status: 1

Looks like we need to be passing only one argument to AC_SUBST,
and that this doubling-up (or 4-at-a-time which we do too) is no
longer valid syntax.
