This works for me:
a.b.c.d    dnscache1.xxxx        # dns=a:www.google.com testip 
depends=(dns:UPSTREAMLINK/conn)

(where UPSTREAMLINK is the name of a bb-hosts entry that has a conn check for 
our next hop(s)).

If UPSTERAMLINK.conn is red, and the dns test fails, it goed clear instead of 
red (well, it can be red for a brief period, so one should alert on red with 
DURATION greater than the time your bbtest-net cycle actually takes - in my 
case the time taken when DNS is unavailable)

If you have a case where it is not working according to the documentation, 
please discuss and file a bug if necessary.

Note though that depends only works for tests run by bbtest-net, AFAIK you 
can't have a network check depending on a ports (client data) check, or have 
one host checked by one bbtest-net instance depend on a network test checked 
by another bbtest-net instance. This is covered in the bb-hosts(5) coverage 
for the 'depends' tag.
