Here is a solution that has worked for me:

1. Install Command Line Tools for Xcode

   Xcode -> Preferences -> Downloads
   

2. Help MacPorts find the right Xcode folder

   sudo /usr/bin/xcode-select -switch /Applications/Xcode.app
   

3. Create symbolic links for clang compilers as they now live elsewhere

   sudo ln -s `which clang` /Applications/Xcode.app/Contents/Developer/usr/bin/
   sudo ln -s `which clang++` /Applications/Xcode.app/Contents/Developer/usr/bin/

Try using trunk, there's no release supporting Xcode 4.3 yet.

Answer 3

As alternative: you can make downgrade of Xcode to 4.2.1 version. DMG of Xcode 4.2.1 placed here: https://developer.apple.com/downloads/index.action

After this MacPorts became works fine for me.

Answer 4

Setting the developer path in /opt/local/etc/macports.conf works for me,

developer_dir /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain

Answer 5

sudo mv /usr/bin/xcodebuild /usr/bin/xcodebuild.old
sudo ln -s /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild /usr/bin/xcodebuild 

Answer 6

This is fixed in MacPorts 2.0.4.

To upgrade:

1. Download MacPorts 2.0.4 from the install site or run sudo port selfupdate.
2. Run the MacPorts migration described here to reinstall all ports. This is painful but required to get back to a working state.
