Sync ports tree
<verbatim>
csup ports-supfile
</verbatim>

Update INDEX
<verbatim>
portsdb -Uu
</verbatim>

Get a list of out-of-date ports
<verbatim>
pkg_version -vl '<' | cut -d' ' -f1
</verbatim>

Pull dependency information for each out-of-date port (Children must be rebuilt/reinstalled as well)
<verbatim>
pkg_info -Rq
</verbatim>

Do this recursively, keeping track of the depth. Once you hit bottom on all the ports and their descendants, squash the depgraph, placing deeper dependencies later. I.e.:
<verbatim>
A
-B
-C
--D
E
-B
-D
=becomes=
A
E
B
C
D
==
</verbatim>

BASH script:
<verbatim>
#!/usr/bin/env bash

 done
}
clear_deps() {
 depth=0
 storevar="list_${depth}"
 eval list=\${${storevar}}
 while [ -n "${list}" ]
 do
  echo "Clearing $storevar"
  unset $storevar
  depth=$(( ${depth} + 1 ))
  storevar="list_${depth}"
  eval list=\${${storevar}}
 done
}
resolve_deps(){

 storevar="list_${depth}"

  then
   resolve_deps $(( ${depth} + 1 )) ${deps}
   depth=$(( ${depth} - 1 ))
   storevar="list_${depth}"
  fi
  shift
 done
}
print_deps() {

 storevar="$(printf "list_%u" "${depth}")"
 eval list=\${${storevar}}
 while [ -n "${list}" ]
