pkg_cutleaves listing needed ports as leaf nodes.....

[Eric Schuele]

Hello,

When I use `pkg_cutleaves -l` to list leaf nodes.  It is listing things 
I know are required by other apps.  These aren't build dependencies.

For example, it lists g-wrap, and libpcap.  If I remove g-wrap, my 
gnucash2 immediately refuses to run.  And I know libpcap was an "option" 
I selected for NTop.  There are others as well.  I have noticed that a 
`make  pretty-print-run-depends-list` is empty for gnucash2.  Is that 
significant?

Why would these not be +REQUIRED_BY something?  `pkgdb -F` doesn't 
mention anything at all.

If something has no +REQUIRED_BY file... how can I go about determining 
why its on my machine or which port installed it?  Obviously top level 
items I installed aside.

Thanks.
