This appears to be an actual boxgrinder bug.  It happens in the
following code:

      @guestfs.aug_init("/", 32)
      @guestfs.aug_rm("/augeas/load//incl[. != '/etc/sysconfig/selinux']")
      @guestfs.aug_load

      selinux = @guestfs.aug_get("/files/etc/sysconfig/selinux/SELINUX") # here

I'm going to assume that the guest's /etc/sysconfig/selinux file
doesn't exist or doesn't contain an SELINUX=... entry.

In any case, you'll need to file a bug against
rubygems-boxgrinder-build giving all the relevant details.
