cant login after make installworld: pam_opie.so.6 not found

Hi All

I am having a problem here after doing a:
make installworld
and
make delete-old-libs

now I cant login (only thru single user)
looks like the "make delete-old-libs"  has deleted that lib pam_opie.so.6 and now I cannot pass the login prompt
says the error "pam_opie.so: not found

how can I get it back? I tried everything and nothing brought it back , not even another make installworld
any insights?

Thanks
