I had a look at it. It is missing those dependencies which are not
installed. Depending on when this target is used, this is ok or not.

Note, there was trackerd running in the background while testing...
For the difference between the redirected output case: I think the
gnome terminal needs a lot of time to print all the lines. But still,
the awk version takes around 3/4 of the time (interesting is the user
time, not the total time). Stephen's version can be speed up some
fractions by inserting a break into the first while-loop.
Attached is my awk-version and the awk version which also includes the
direct dependencies.
Bye,
Alexander.
