freebsd stable - May 2005 - pkg question...

Is there a way to remove a package and the dependencies that only said
package uses?  

For example, I have package A which depends on B, C and D.  Furthermore,
I have package E depends on C.  I want to get ride of package A in such
a way as packages B and D get deleted too but not package C.   

Can this be done at all?  

I've looked at portsclean and libchk but neither really suits what I
want.  Unless I have mis-read something. 

Thanks.
