keybounceMBP:Mlp michael$ port dependents xorg-libX11
gdk-pixbuf2 depends on xorg-libX11
mesa depends on xorg-libX11
xorg-libXext depends on xorg-libX11
xorg-libXfixes depends on xorg-libX11
xorg-libXt depends on xorg-libX11
xrender depends on xorg-libX11
keybounceMBP:Mlp michael$ port dependents mesa
mesa has no dependents.
keybounceMBP:Mlp michael$ port dependents gdk-pixbuf2
gtk2 depends on gdk-pixbuf2
keybounceMBP:Mlp michael$ 

Hmm, so mesa is one of them, and nothing depends on mesa (so who asked for it / why is it there?)

But also gtk2. I thought gtk3 was the current version -- gtk2 isn't even maintained if I understood correctly.

keybounceMBP:Mlp michael$ port dependents gtk2
gtk2 has no dependents.

And who asked for it?
