Problem Installing Python27 on El Capitan

[ruchi.gupta345@…]

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:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_python27/python27/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port python27 failed

Please find main.log in the attachment. Please help me sort this out.

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                     ^

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.
