which ports require dialog during update

[Paul Macdonald]

Hi,

Is there a way to tell which ports might require dialog input during update,

i have some auto update scripts which when prompted will run through 
updates, but occassionally i forget which will require user input and 
this leads to dialog running ( often @ 100%) until i notice.

Obviously i only do this for what i'd consider to be trivial updates and 
it makes things a lot quicker when you have a lot of boxes to do!

I had initialy thought that checking for make targets might be an idea, 
the lack of a config target for example.

On one box which does have a config/options target, i see options come 
up via dialog.

/usr/ports/security/p5-IO-Socket-SSL
     brings up the config options for this port, both unchecked

[ ] IDN   International Domain Names (IDN) support       x x
[ ] IPV6  IPv6 support

on another box there's no dialog from either an update via portupgarde 
or via a direct make in the port dir  ( make config is the same on both 
and does bring up the dialog)

the Makefiles are identical both in the ports dir and in the work dir, 
both systems are 8.2-REL.

Can i programmatically tell if user input is required?

thanks
Paul.
