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.

There are a lot of packages in Xcode

to-do additional installer flag

 [-showChoicesXML] [-applyChoiceChangesXML <pathToFile>]
 [-showChoicesAfterApplyingChangesXML <pathtoFile>]

install (use gui, cli still incomplete /Developer/Library, etc.)

hdid ~/Downloads/xcode_3.2.6_and_ios_sdk_4.3.dmg
