 duti fails to build, for example on 10.10:

 https://build.macports.org/builders/ports-10.10_x86_64-builder/builds/127170/steps
 /install-port/logs/stdio

 {{{
 clang: warning: no such sysroot directory:
 '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk'
 }}}
 {{{
 ./util.c:1:10: fatal error: 'CoreFoundation/CoreFoundation.h' file not
 found
 #include <CoreFoundation/CoreFoundation.h>
          ^
 }}}

 It is wrong for the build to try to determine what SDK to use. MacPorts
 will tell the build what SDK, if any, should be used; the build should not
 second-guess that.

 The problem here happens because on 10.10 we are using Xcode 7.2.1 which
 does not contain the 10.10 SDK and only contains the 10.11 SDK. For years
 Apple has been introducing new versions of Xcode that contain only the
 latest OS SDK, even if that version of Xcode runs on the previous version
 of the OS.
