Mat,

You may want to use VisibleDepend instead of Depend.  Depend hides the
.pkg info in BlueLinQ until the dependency is met, where VisibleDepend
doesn't.

The syntax is:

VisibleDepend:	<Vendor>:<Name> <compare> <Version>

compare is a combination of =, > and <.  The version is a real number.

The perl regular expression used to parse this is found in SWUpdate.pm:

  if (/^Depend:\s*(\S+):(\S+)\s*(?:([!>=<]*)\s*(\S+))*/i) {

and:

  if (/^VisibleDepend:\s*(\S+):(\S+)\s*(?:([!>=<]*)\s*(\S+))*/i) {

An example, (from Qube 3 OS Update 2's packing_list):

Vendor:                Cobalt
Name:                  OS
Version:               6.2
VisibleDepend:         Cobalt:OS = 6.1
