dnl Recently, we need -lber even though the main routines are elsewhere,
dnl because otherwise be get link errors w.r.t. ber_pvt_opt_on.  So just
dnl check for that (it's a variable not a fun but that doesn't seem to
dnl matter in these checks)  and stick in -lber if so.  Can't hurt (even to
dnl stick it in always shouldn't hurt, I don't think) ... #### Someone who
dnl #### understands LDAP needs to fix this properly.
