(I'm replying 'cos I think I contributed the start of the 'dependancy' 
code...)

The 'dependancy' just adds the packages to the list, which is then 
installed in order of priority. If 'foo' depends on 'bar' being present 
for 'foo' to install properly, 'bar' ought to have a higher priority than 
'foo'.

In the example above, B should be set at a higher priority than A for 
success. (I usually have 900-999 as the priority for OS patches, 700-799 
for antivirus etc, 500-599 for 'mission critical' applications, 300-399 
for useful things and 100-199 for end-user things like office. Even 
numbered centuries are 'reserved for future expansion'...)

Yours,

Frank
