I'm sorry that I have been unable to show you the script delivers
exactly what you want. To find slave ports of a port you could do:

  awk -F\| -v MASTER="mail/qmail" '$1 == MASTER "/Makefile" {print MASTER " -> " $3}' $DEPENDSFILE

with a result of:

  mail/qmail -> mail/qmail mail/qmail-ldap mail/qmail-mysql mail/qmail-smtp_auth+tls mail/qmail-tls


To find master ports, just do:

  grep '^[^/]*/[^/]*/Makefile|' $DEPENDSFILE |
  awk -F\| -v SLAVE="mail/qmail-mysql" '$3 ~ "(^| )" SLAVE "( |$)" {sub("/Makefile$", "", $1); print $1}'

Result:

  mail/qmail-mysql
  mail/qmail

(in this example you have to quote metacharaters in SLAVE, like 
 SLAVE="mail/qmail-smtp_auth\\+tls", but that is an problem of
 awk, not the database.)

Besides, you have to feed the list of updated files to some script
to update the debedency database, which won't work with a pure
`make -V' solution.

The database has more information, like that 149 ports depend on
x11/kde3/Makefile.kde, but if you don't want to know then simply
don't ask.

Tell me some names, and I will tell you what my script delivers. You 
still owe me a sample where my script is wrong.

I guess this patch is fine.
