Comment (by jasoncampisi+macports@…):

 I have had this same problem building cmake in OS X.X Beta 1 through OS
 X.X Goldmaster with no luck fixing the problem. I only care about cmake,
 so I can install WINE.

 I have done the following:

 1. Completely uninstall Macports. Remove all traces using these steps
 [https://guide.macports.org/chunked/installing.macports.uninstalling.html
 guide.macports.org/chunked/installing.macports.uninstalling.html]
 2. Reboot the system
 3. Download and build Macports from the latest source (I tried using the
 binary install route with no luck fixing this problem). Guide here
 [https://guide.macports.org/chunked/installing.macports.html#installing.macports.source
 guide.macports.org/chunked/installing.macports.html#installing.macports.source]
 4. Next, run the command: ''sudo port install cmake''

 Note: these steps, assume you already installed
 1. Xcode 6
 2. Xcode 6 Command-line tools and agreed to the Xcode license: ''sudo
 xcodebuild -license''
 3. X11 via the XQuartz project [http://xquartz.macosforge.org/
 http://xquartz.macosforge.org]

 After investigating the below log fragment, I am left with the question,
 how do I '''set CMAKE_OSX_DEPLOYMENT_TARGET to empty''', as a means to get
 around this problem?

 My error log includes this detail:[[BR]]
