New description:

 The last supported Xcode for 10.11 is 8.2.1:
 {{{
 Xcode 8.2.1
 Build version 8C1002
 }}}

 My attempt to build MacPorts-2.8.1 on this machine fails as:
 {{{
 make[2]: Nothing to be done for `all'.
 ===> staging to destroot in vendor/tcllib
 /tmp/macports/MacPorts-2.8.1/vendor/tclsh `echo ./installer.tcl` \
                 -pkg-path   `echo /tmp/macports/MacPorts-2.8.1/vendor
 /vendor-destroot/opt/local/libexec/macports/lib/tcllib1.21` \
                 -no-examples -no-html -no-nroff \
                 -no-wait -no-gui -no-apps
 dyld: lazy symbol binding failed: Symbol not found: _os_unfair_lock_lock
   Referenced from:
 /tmp/macports/MacPorts-2.8.1/vendor/tcl/unix/libtcl8.6.dylib (which was
 built for Mac OS X 10.12)
   Expected in: /usr/lib/libSystem.B.dylib

 dyld: Symbol not found: _os_unfair_lock_lock
   Referenced from:
 /tmp/macports/MacPorts-2.8.1/vendor/tcl/unix/libtcl8.6.dylib (which was
 built for Mac OS X 10.12)
   Expected in: /usr/lib/libSystem.B.dylib

 make[2]: *** [install-libraries] Trace/BPT trap: 5
 make[1]: *** [destroot-tcllib] Error 2
 make: *** [all] Error 1
 }}}
 because it uses  `os_unfair_lock_lock` on macOS 10.12+

 So, the simple test program:
 {{{
 #include <AvailabilityMacros.h>

 #include <iostream>

 int main() {
     std::cout << "MAC_OS_X_VERSION_MIN_REQUIRED: " <<
 MAC_OS_X_VERSION_MIN_REQUIRED << std::endl;
     return 0;
 }
 }}}
 has an output: `MAC_OS_X_VERSION_MIN_REQUIRED: 101200`

 BTW`./configure CFLAGS=-mmacosx-version-min=10.11` helps
