Do they build the same output with different features?

Port A with and without +foo builds lib-A.dylib

And not, Port A without +foo builds lib-A.dylib and with +foo builds lib-A.dylib & lib-A-foo.dylib?

IIRC the subversion-bindings ports didn't initially have nice 'install' targets, so we manually cleaned up post-destroot so that they would just have the additional libs that were necessary. The actual 'build' ends up duplicating some build products that don't get installed for the bindings ports (because they're already installed by the main port) - but it's worth it to have everything "just work" for our end-users.
