How to do some cleaning on ports ?

[SPlissken]

Hi all

I have lot and different versions of same ports installed on my desktop machine
Why do i have differents versions of same ports ? autoconf is an example of this.
Is there a way to show packages i could surely remove , i mean needed by no other packages ?

Some ports require version A while others require version B.

ports-mgmt/pkg_cutleaves

Also ports-mgmt/portmaster and ports-mgmt/portupgrade have options to weed out/identify stale ports.
