Warning: The Command Line Tools For Xcode Don't Appear To Be Installed; Most Ports Will Likely Fail To Build

I was trying to actually Install biopython on my new mac. Python 2.7 is already installed in it. To install biopython I found is good to install with macports. Now to install macpo

Solution 1:

You can get Xcode from the Mac App Store as a free download. From within that (in the preferences | downloads) you can download and install the command line tools.

You might also need to tell the command line tools to use the versions within the Xcode app bundle rather than those in /Developer which aren't there with the new package based install.

Run this from the Terminal:

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

Solution 2:

Don't forget what I forgot: After installing Xcode 4.3, the Command Line Tools must be installed. This is done from the Downloads section of Xcode's preferences!!!
