I'm trying to install MacPorts but it needs command-line support to be installed with Xcode (which is an option during installation)

is there any way I could install UNIX comm开发者_C百科and line support with Xcode without re-installing Xcode?

Reinstalling Xcode is non destructive so best to just do that. Your projects will all still be available.
