Unable to get MacPort functionality after installing Xcode 4.3

Question

I am having trouble getting MacPorts to function properly. I just installed OSX Lion 10.7.3 I downloaded and installed MacPorts first, and then after reading the requirements, I downloaded Xcode4.3 from the App Store, and then installed it. I launched Xcode and it looks to be operational and functional. However when I attempted to port with MacPorts, it gave me this error message(excerpt):

Warning: xcodebuild exists but failed to execute Warning: Xcode does not appear to be installed; most ports will likely fail to build. 

I followed the advice from:

How do i install additional packages for Xcode on OSX Lion to allow MacPorts to work

and installed command_line_tools_for_xcode from the Preferences within Xcode. I closed Xcode, and again got the errors:

$ sudo port install libsocketsPassword: Warning: xcodebuild exists but failed to execute Warning: Xcode does not appear to be installed; most ports will likely fail to build. --->  Computing dependencies for libsockets --->  Dependencies to be installed: openssl zlib --->  Extracting zlib Error: Couldn't determine your Xcode version (from '/usr/bin/xcodebuild -version'). Error:  Error: If you have not installed Xcode, install it now; see: Error: http://guide.macports.org/chunked/installing.xcode.html Error:  Error: Target org.macports.extract returned: unable to find Xcode Error: Failed to install zlib Log for zlib is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_archivers_zlib/zlib/main.log Error: The following dependencies were not installed: openssl zlib Error: Status 1 encountered during processing. 

I am uncertain where to go next with this. How do i trouble shoot my Xcode and MacPort interface?

Answer 1

In theory this should work if you have Xcode4.3 installed (in /Applications):

$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/ 

(And you've installed the optional command line tools)

Answer 2

Everything will start working fine after installation of "Command Line Tools for Xcode" package. You can get it from here: https://developer.apple.com/downloads/index.action#
