gnome2 and packages cleanup

[Gareth Campbell]

Hey everyone,

I was installing gnome2 from the ports collection (on dial-up!) and it 
took like 3 days of constant work when it finally ran out of space on my 
/usr drive (only using a 6.4gig).  I thought this would be more than 
enough, but alas...  So I guess Gnome is too much for my wee system so I 
want to go back to using enlightenment.  My issue is that now my system 
is full of packages that I don't need.  How do I clean up my system of 
all of these packages without deleting packages that enlightenment uses??

Thanks
