If I build Coin +aqua, SoQt must also build for aqua and depend on Coin +aqua. It also holds that if Coin is built with X11, SoQt must also build with X11 and depend on Coin (X11). Would it make sense to add SoQt as a sub-port of Coin? I'm not the maintainer so I created a separate Portfile for SoQt. How do I handle this as a separate port? Mark
