Try the port_cutleaves port.

Not directly. You can use the output of `port echo installed` with a
little scripting.

i686-apple-darwin9-gcc-4.0.1 is part of Apple's gcc 4. It's what you are
compiling with, not what you're compiling. If you want to see which port
installed a file, use `port provides /path/to/file`. If you want to see
why that port is needed, use `port dependents portname`.
