You still don't have a working compiler. You need to install Apple's dev 
tools to obtain one. "port info gcc42" just provides the information 
about the port, it doesn't mean the port is installed.

I know this seems counterintuitive, since MacPorts pretty much builds 
all of its own stuff and tries not to depend on anything 
Apple-installed, but Apple's gcc is one of the foundational things it 
needs to bootstrap itself.
