 Dear Experts,

 I need to install python27. I am using 'sudo post install python27' (I
 also did 'sudo port clean python27').
 I am getting following error.
 {{{
 Error: org.macports.destroot for port python27 returned: command execution
 failed
 Please see the log file for port python27 for details:

Comment:

 The log shows many compilation errors starting with:

 {{{
 :info:destroot
 /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:19:21:
 error: expected a type
 :info:destroot - (id)copyWithZone:(nullable NSZone *)zone;
 :info:destroot                     ^
 :info:destroot
 /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:25:28:
 error: expected a type
 :info:destroot - (id)mutableCopyWithZone:(nullable NSZone *)zone;
 :info:destroot                            ^
 }}}

 It also shows that your clang version is 600.0.57. According to
 XcodeVersionInfo, that's from Xcode 6.2. That's too old to be compatible
 with El Capitan. You need to upgrade to Xcode 7 or later. If you've
 upgraded to El Capitan from a previous OS X version, make sure you've
 followed all the steps in wiki:Migration. Upgrading Xcode is step 1.
